System Hangs on X-kill, reboot, or shutdown [an fglrx problem].

I'm pretty sure this is linked with my new monitor somehow. I got a new monitor, its hooked up with the DVI cable. Whenever I try to:
exit openbox
ctrl-alt-backspace to kill x
restart (shutdown -r now)
or shutdown (shutdown - now)
my system hangs. My screen shuts off, and starts blinking the power button, and its not responding.

I've no idea whether it's possible for a new monitor to somehow cause this... are you running ATI or nVidia drivers? Is direct rendering working, do you know?
Try doing
$ sudo chown -r yourNonRootUser /path/to/yourNonRootUsersHome
and seeing whether that remedies the problem with exiting openbox.
Also, look in /var/log/ for your Xorg.#.log files (I forget whether they're in a subdirectory in there... maybe under /var/log/x11/ ). See whether the most recent log file has any warnings or errors (EE or WW in brackets) that may indicate the source of the problem.

System hangs at POST after reboot

I have a Dell L400 laptop (p3 700mhz 256mb 20gb hd) and have sucessfully installed arch along with xfce and a few other programs. Everytime I reboot via "reboot" cmd or through xfce, the system unmounts everything and reboots but hangs at the POST screen. I cant get into bios or the boot option menu either. I also have a stripped down windows xp installed (before arch) and i can reboot from there. any ideas on whats going on?

Hi, I have exactly the OPPOSITE problem from you. Windows won't do a warm restart - hangs after the POST. Arch WILL do a warm restart. I still haven't figured it out. I am assuming that Windows is messing up something in the hardware that mucks up the restart and Arch isn't. Since you and I have different hardware for sure, you are likely experiencing the same sort of problem, but from a different source!
In my case, a simple power cycle resolves the problem and Windows boots properly. However, it will only boot from a power on. It will never boot from a warm restart.

System hangs on shutdown

First, the source of the problem was the startupitem for mysql.
I removed all system startup items then rebooted fine, after that I eliminated all the options by placing them back 1 by 1.
What I find strange was that I moved the mysql startup item to the startup folder, set the permissions right and reboot.... And the system immediatly hung... Why is this (called) a startup item if it affects shutdown?
And how can it affect a shutdown like that.... How exactly are the startupitems used during shutdown?
MacBook Mac OS X (10.4.8)

How can something that isnt started, refuse to shut down?
I dragged the mysql startup item to the startup folder and the system hang at the next reboot..... So it couldnt have been started right?

Are FF4.0.12 and Adobe win,2,159,1 compatable? Since I updated both 5 days ago, I cannot use Facebook or play games. Adobe says it is a FF4 problem so I downloaded 3.6.17 but no help. System hangs.

XP, 128 bit,ff3.6.17 now but no help.
Since I updated both, in Facebook my system hangs repeatedly
Only hard reboot and open new session will let me back on. I have been talking to Adobe support for 3 days and got the advice to put FF3.6.17 back on. It is worse when trying to scroll or trying to play a game. Cursor freezes and system hangs. I need some help pls. Which plugin is best when trying to use facebook and games on FF4.12? DOESN'T ANYONE KNOW OF ANY HELP? Just give me the name of a plugin that FF likes and a Web address. I need to be able to use my browser and would like to play some of my games. PLEASE!!!

Hey, I really need some help. Doesn't anyone know?
Just tell me a plugin that will work and not hang FF and give me a website. PLEASE.

Just updated to Yosemite, can't update or uninstall adobe flash, system hangs

Just updated to Yosemite, can't update or uninstall adobe flash, system hangs, have to force quit,.
Is this a problem with the new operating system and how do I fix this?

If you can't install or update Flash, follow these instructions.

[915 Series] System hang when installed CoreCenter

After updated bios to version 1.7 and Core Center 2.0, my system hang after sometime running.
When uninstalled CoreCenter, no problem now.
If installed previous version Corecenter, it still hang.

Many people here will tell you to dump CoreCenter. I don't use CoreCenter either. You'll find many here use Speedfan or MBM5 to monitor their temps and voltages. MBM5 is no longer developed and won't support your mobo. Speedfan is still updated and you also can control fans with this utility. Are soft OC'g with CC? Software OC'g is not recommended, but if you do soft OC, Clockgen is better program for doing so. I wouldn't. OC'g using the bios is considered the better method.
Also, it's a good idea to read the stickies especially the one about posting. As stated in the post I linked to, please include information about your system. See that post and my signature as an example.

System hangs on reboot/shutdown after kernel upgrades

I've been experiencing the problem that, whenever pacman upgrades the kernel, the system hangs on reboot or shutdown. It only happens on the first reboot/shutdown after a kernel upgrade. I've noticed it consistently for a while now.
To reboot, I issue:
# reboot
To shutdown, I issue:
# shutdown -h now
I should also mention that I typically reboot after kernel upgrades because hotplugged storage devices (USB, SD) fail to be detected unless the system reboots. That is, devices plugged in during the upgrade remain usable, but plugging in something new appears in /dev. There may be an obvious reason for it that I'm missing, but it's never bothered me enough to look into it. Not sure if this and the reboot/shutdown issue are related, though.
Any ideas would be greatly appreciated. Thanks!

When Apple Hardware Test says there is a problem, there definitely is a problem.
But like many diagnostics, it does not catch everything.
It can increase your confidence that you do not have gross flaws. The Hardware problems that remain may be more subtle ones.

System hanging on shutdown

The home directories on my system are on NFS.
Most of the times, when users log out of their graphical session, some of their processes keep running (for instance /usr/bin/nepomukserver for KDE users and some processes related to pulse or to chromium).
When shutting down the system, arch scripts first try unmounting network filesystems, and this fails, since /home is busy; then they send a SIGTERM to processes, and this fails as well (I believe it's because the network has been halted but /home hasn't been mounted), then the system hangs while unmounting non-API filesystems.
If, before shutting down, I manually kill the user processes (nepomukserver, pulse, chromium, ...), arch is able to shutdown as expected.
Am I the only one affected by this problem?
How am I supposed to solve it?
I'm thinking about writing a script to terminate (`kill` and then `kill -9`) any process using /home (`lsof /home`), but this looks like a terrible hack...

So, since I couldn't find any other solution, decided to write a script (an init script to add to the DAEMONS array) that kills the processes using /home while halting the machine...
If anybody will ever need it, here it is:
/etc/rc.d/pathliberator
#!/bin/bash
# Path Liberator
# kills processes that are using a given path
DAEMON=pathliberator
. /etc/rc.conf
. /etc/rc.d/functions
[ -r /etc/conf.d/$DAEMON ] && . /etc/conf.d/$DAEMON
case "$1" in
start)
stat_busy "Starting path liberator"
add_daemon $DAEMON
stat_done
stop)
success=true
for path in ${PATHS_TO_LIBERATE[@]}
do
pids=$( lsof -Fp $path | sed -rs "s/^.(.*)$/\1/g" )
if [ "$pids" == "" ]
then
status "$path was already free" true
continue
fi
# kill -TERM
stat_busy "Liberating $path"
kill -15 ${pids[@]} &>/dev/null
pids=$( lsof -Fp $path | sed -rs "s/^.(.*)$/\1/g" )
if [ "$pids" == "" ]; then
stat_done
continue
fi
stat_fail
pids=$( lsof -Fp $path | sed -rs "s/^.(.*)$/\1/g" )
# kill -KILL
stat_busy "Liberating $path with SIGKILL"
kill -9 ${pids[@]} &>/dev/null
pids=$( lsof -Fp $path | sed -rs "s/^.(.*)$/\1/g" )
if [ "$pids" == "" ]; then
stat_done
continue
fi
stat_fail
success=false
done
status "Paths liberated" $success
if [ $success ]
then
rm_daemon $DAEMON
fi
restart)
$0 stop
$0 start
echo "usage: $0 {start|stop|restart}"
esac
exit 0
/etc/conf.d/pathliberator
# Parameters to be passed to pathliberator
PATHS_TO_LIBERATE=(/home/)
It seems to be working, although didn't deeply test it...
My DAEMONS array now looks like this:
DAEMONS=(hwclock syslog-ng cpufreq network crond nscd dbus rpcbind nfs-common netfs pathliberator gpm sshd @ntpdate alsa fuse gdm avahi-daemon)

Lion 10.7.1 system hangs after reboot

Strange, I have just updated to 10.7.1 (via SW update) on my Macbook Pro and now the system does not boot. It restarted and now hangs since minutes with the spinning wheel on a grey screen. Anyone experienced this, too? Any solutions?
Thanks a lot.
Tom

Regarding the occasional system hang on reboot people are experiencing. I have two troubleshooting suggestions to help you get to the login screen, but aren't solutions to the problem of whatever is causing the system hang. 1) I find my hangs are usually solved by removing my USB devices from the 2 USB ports (via USB hubs) and rebooting. 2) Furthermore, if I boot into verbose mode (holding command+v right before the chime) (sometimes after removing the USB devices, sometimes not), that usually helps the boot process along, either due to just chance (I don't know why booting into verbose mode would help it surmount the initial hang, but it seems to work sometimes) or some other reason.
Good luck.
Yeah that better be one big fat good luck there, because that advice is not going to help anyone that is having this problem. Not one little bit. Some kind of magic that Verbose Mode casts will fix it? Uh, no. That would be a figment of your over-eager imagination, Verbose Mode doesn't change anythig. Oh and by the way, in order to get to this stage in the probelm, you would have had to use verbose mode to get the error message. I can only assume that you sir are the real troll here, because our friend above asked a question that is worth merit and consideration, given the compatibility disaster that Apple has on their hands. To call it a disaster is not in the least bit an exaggeration.
We're going to have to ignore This is not an "occassional system hang", this is a serious problem affecting my MacBook Pro 17" and my iMac 27"., and it occured on both of them for me after installing Lion Server.

Hang when reboot or shutdown

Hi
I'm just install arch linux it's work fine, until reboot or shutdown, it's hang after text "storage is finalized." as picture.
http://www.temppic.com/img.php?12-09-20 … 164500.jpg
please tell me how should i do? i tried it for 2 days.
Thanks.

Hi, every body.:)
After I change my hardware(same model), I try to follow the web carefully.
Please read my step and tell my mistake. If you see it.
1. This picture is boot from CD, It's not have "Boot Arch Linux x86_64 " menu because my motherboard not have UEFI firmware, right or not? pleae tell me.
1. Using fdisk to create MBR partitions. It's have 2 partitions. No swap partition.
2. mkfs.ext4 /dev/sda1 and 2
3. mount /dev/sda1 /mnt
4. mkdir /mnt/home
5. mount /dev/sda2 /mnt/home
6. nano /etc/pacman.d/mirrorlist for edit mirrorlist
7. pacstrap /mnt base
8. genfstab -U -p mnt >> mnt/etc/fstab
9. nano /mnt/etc/fstab for check fstab
10. arch-chroot /mnt
11. nano /etc/locale.gen for configure font.
12. echo LANG=en_US.UTF-8 > /etc/locale.conf
13. export LANG=en_US.UTF-8
14. echo myhostname > /etc/hostname
15. pacman -S syslinux
16. syslinux-install_update -i -a -m
17. nano /boot/syslinux/syslinux.cfg for change "APPEND root=/dev/sda3" to sda1(fallback too)
18. pacman -S grub
19. grub-install --target=i386-pc --recheck --debug /dev/sda
20. grub-mkconfig -o /boot/grub/grub.cfg
21. exit (chroot)
22. umount -R /mnt
23. reboot
Then this picture happened.
And It's not reboot except off the power switch.
After power on again I continue follow the same web.
24. pacman -S xorg-server xorg-server-utils xorg-xinit
25. pacman -S mesa
26. pacman -S xf86-video-vesa (I can't find correct driver.)
27. pacman -S xf86-input-synaptics
28. pacman -S xorg-twm xorg-xclock xterm for install default environment.
29. Try "startx" and my display here.
30. exit.
31. shutdown -h now, here's the result.
Still hang in this step.
Please tell me my mistake.

Odd System Hangs [SOLVED]

I have a cleanly installed Arch (x86) system on a Dell Vostro 1500
Intel 2.5 GHz Core 2
Braodcom Wireless (ndiswrapper)
4GB Ram
250 GB Western Digital HDD (sata)
nvidia 8400 GS 256 MB
1650x1080 Resolution
Built in UVC web cam
I seem to be having these completely random and odd system hangs.
It prevents me from using my computer for more than a few minutes at a time.
When it hangs, its usually what ever process im in gets stuck, i cant kill it completely all the time. Sometimes i can using top as root and sometimes i can using kill -kill but sometimes i cant at all and that is usually when the PPID is 1.
When I try to shutdown or reboot either from in gnome or one of the virtual consoles, it always says something about either the root or home partition unable to be unmounted, that they are still busy.
my partition layout is such:
sda1 NTFS Vista (I have to have it because of stupid itunes/iphone)
sda2 ext2 boot
sda3 xfs root
extended:
sda5 xfs home
sda6 swap swap
my ntfs partition is about 50GB and when i boot into vista i dont get the same hangs, so i don't think its a hard drive issue (but could be an partition issue)
boot partition is something like 300MB
root is something like 12 GB
Home is something like 70 gb
and swap is about 2gb
It does not matter whether or not im in gnome since if at log in screen, ill hit ctrl+alt+f1 and switch to a consol and do something as simple as like update the computer and ill cause it to hang sometimes (but not every time its too unpredictable)
When in gnome however, most applications refuse to launch and sometimes even close. The gnome-panel and some (like the system monitor) lock up but things like cpu freq scaling continues to work as does log out and the menu.
i have also had issues with the latest (-3) nvidia driver and can only get 1680x1050 resolution using the open source nv drivers (haven't had a chance to build from aur the beta drivers yet since there is an issue with the nvidia-utils-beta package) but i don't think this is causing it.
i used the western digital tool to do a hard drive scan, and it didn't find anything in the quick scan but it is still running the full scan.
I suspect it might be due to some package upgrade, i was running arch before the reformat and it was causing me to have the same issues.
i have kicked my personal Ubuntun (and derivatives) additional because of Arch's rolling release cycle so that's why i would rather put up with it for another week to figure this out!
Let me know if there is any log files i should post or anything that way i can get this fixed! And thanks in advanced (even to those of you who will probably only comment to make fun of vista, it still will keep my thread alive! )

IBM OS ISSUE: SYSTEM HANG WITH JFS2 AND HEAVY LOAD
==================================================
PURPOSE
이 문서는 IBM AIX5L OS 상에서 Arch Process가 online redo log
를 release하지 못하고 OS의 kill 명령으로 kill조차 되지 않을 경우
조치 방법이다.
Problem Description
이 문서는 다음 OS 정보와 Oracle version인 경우에 해당한다.
Oracle Server - Enterprise Edition - Version: 9.2.0.5.0
Oracle Server - Enterprise Edition - Version: 8.1.7.4.0
AIX5L Based Systems (64-bit) or (32-bit)
문제 발생 당시의 증상은 다음과 같다.
- arch-process doesn't release redolog files
- arch-process doesn't die after database shutdown
- arch-process can't be killed
genclntsh 수행 시 hang 상태이다.
(sleeping...)28590: kwaitpid(0x2FF22470, -1, 4, 0x00000000, 0x00000000)
또는 이 문제로 인하여 ORA-600[2103] 에러가 발생하기도 한다.
이 에러가 발생하는 원인은 IBM AIX5L 64bit, 32bit OS 이슈에 있다.
IBM OS issue: SYSTEM HANG WITH JFS2 AND HEAVY LOAD.
Workaround
none
Solution Description
OS AIX5L ML4.0(5.2.0.40)의 bos.up / bos.mp / bos.mp64 fileset level을
갖는 JFS2 file system을 갖는 경우에 해당한다.
AIX 5.3 APAR IY59387은 IY58143에 포함되어 있다.
JFS2 file system에 Heavy I/O activity가 발생하면 database process에
HANG 문제를 야기시킬 수 있다. 이 때 database process가 kill -9
명령으로 kill되지 않는다. 데이타베이스를 SHUTDOWN하여도 Process가
계속 살아 있게 된다.
Process에게 SIGKILL 함수가 issue되었지만 영향을 주지 않게 된다.
Process를 제거하는 유일한 방법은 OS를 reboot하는 것이다.
문제를 예방하는 방법은 IBM APAR-FIX IY59082 를 적용하는 것이다.
이 APAR는 bos.64bit 5.2.0.42에 포함되어 있다.
Fix :
Need to install the IBM APAR-FIX IY59082, this APAR is included on
bos.64bit 5.2.0.42.
(주) IBM 엔지니어에게 확인 결과 이 Patch 안에 AIX5L 32bit 용과 64bit
용이 모두 포함되어 있는 것으로 확인됨.

b,
The install was from my original Dell XP Pro-SP1 'Reinstallation' CD along with the complete MS XP-SP2 download that I burned to another CD. I also had all the latest Dell drivers from their website burned to a CD. Install went as follows:
- Format HD
- Install XP Pro SP1
- Install SP2
- Install Dell Drivers
- Obtain any MS patches from their site
- Install Office
- Update Office from the MS website
- Install iTunes
- Tweak MS settings
- Install many software programs
- Make an interim Image of system and store to ExHD
- Install other software programs (mostly security programs)
- Make another 'complete' Image to ExHD
- Restore backup data and music
After additional testing last night, I determined that it is not iTunes at all (or to blame). I get intermittent hangs/freezes/pauses in other media players (WMP, etc.).
Seems that something is causing the 'System' process to periodically jump up in CPU %age (though not more than 30-50%). Even this relatively small amount is enough to pause the playback of music or video, hang the mouse movement for a brief moment, or delay a menu opening. All very subtle - you have to be looking for it to notice (except with real-time audio-video, which is quite noticeable whenever this happens).
I had this problem a year ago, which is why I reimaged then and stayed with SP1 on the advice of Dell and Webroot. I'm stumped as to where to look for the culprit. Every time I go back to the original HD with SP1, everything runs smoothly. Some sort of system call is generating this complete pause....
I'll be limited in my Internet ability for the next several days, so I may be out of touch until Friday. I'll keep testing and playing with the limited equipment I take along....
Any thought you or others want to toss out, I'll attempt when possible.
Thanks!

I cant reboot. Shutdown freezes at sending SIGTERM to processes

I could use some advice. For the past 4 months or so I have not been able to do a full shutdown or reboot. When I run the shutdown -r now or reboot commands the process starts but freezes at Sending SIGTERM to processes. At this point I can switch to diffrent terminals with Ctrl+Alt+F? but I cant type.The only thing I can do is hold my power button down to shut off. I have been searching online fore awhile and restored my rc.shutdown script to the original backup I have from months ago but I am still having the same issues. Ill attach my local and shutdown scripts
Thanks for taking a look.

How to run a script automatically just before Reboot or Shutdown

Hello all,
Could someone tell me what folder or what entries to be made if I want an event to take place before the machine actually start the reboot/shutdown process. For instants, i usually mount my USB flash drive but sometime I forget to umount it, which will cause a dirty file system when restarting the machine. Would anyone have an example to get me going. It's just like when rc.conf will do added things for you during start-up if special code/script was inserted.
There are other things I like to do before the machine reboot or shutdown, like, to run a very small scripts to automatically kill a certain process "first", before the rest and before rebooting. I'm sure I can write the code but I don't know where it goes.
Thanks in advance
PS: Thanks fsckd, Your explanation of SKIP/SEEK for dd has never been explained so well in any documentation, or on ANY web-site I ever been to in 6 months pass. Now I know how it really works and i'm getting it down to a science. I did not use it for what my thread indicate because in the end the other suggestions were better, but still I Thank God I finally know how to use SKIP/SEEK in dd. dd is my most use tool for what I do.

There something new every day to learn with this OS. Just when you get one thing right here's comes another. I guest it took 20 years to build LINUX and I read the kernel has something like 10 - 30 million lines of code or better. Some how I lost the better link that went much deeper. 30 million lines of code mean billions of documentation to read. But you still got to find the right one first. So I guest we read and still have to ask questions just to get to the good parts, and than ...

Arch should already automatically unmount your USB drive. If it isn't unmounted, that's a bug and ought to be filed at http://bugs.archlinux.org

System hanging when it runs out of memory

Hello,
my system has a finite amount of RAM and swap (it doesn't matter, to my purpose, if it's 16GB or 128MB, I'm not interested in increasing it anyway).
Sometimes my apps completely use all the available memory. I would expect that in these cases the kernel kills some apps to keep working correctly. The OOM Killer exists just for this, doesn't it?
What happens, instead, is that the system hangs. Even the mouse stops working. Sometimes it manages to get back to life in a few seconds/minutes, other times hours pass by and nothing changes.
I don't want to add more memory, I just want that the kernel kills some application when it's running out of memory.
Why isn't this happening?
Right now I'm writing a bash script that will kill the most memory-hungry process when available memory gets below 10%, because I'm sick of freezing my machine.
But why do I have to do this? Why do I need an user space tool polling memory usage and sentencing applications according to a cheap policy? What the hell is wrong with my OOM Killer, why isn't it doing is job?!

Alright, you won, now quit pointing out my ignorance
Your awkish oom killer is a lot cooler than mine, switching to it, thanks!
I did some testing (initially just to test the oom killing script) and found out that if a program tries to allocate all the memory it can, it gets eventually killed by linux's oom killer. If instead it stops allocating new memory when there are less than 4MB of free memory (or similar values) the OOM won't do anything, and the system will get stuck, like if a forkbomb was running.
That's it, this program with MINSIZE=1 will be killed, while with MINSIZE=4MB will force me to hard reboot:
#include <string.h>
#include <stdlib.h>
#define MINSIZE (1024*1024*4) // 4MB
int main( )
int block = 1024*1024*1024; // 1GB
void *p;
while( 1 ) {
p = malloc( block );
if( p ) {
memset( p, 85, block );
else if( block > MINSIZE ) {
block /= 2;
return 0;
Guess I'd need to go deeper to understand why Linux' oom killer works like that, but I won't (assuming the oom killing script will behave).

System Hangs on X-kill, reboot, or shutdown [an fglrx problem].
