Mkinitcpio hanging on kernel update

I'm getting the latest packages and I'm running into an issue where the image keeps hanging after I install the latest linux kernel.
$ sudo pacman -S linux

This is where it hangs. I let it sit for about 10 minutes when I did the full system upgrade, and then killed it when it looked like it wasn't doing anything. The output above is from the second time this has happened, and I'm not so sure I want to reboot without this getting built correctly.
Any ideas?

OK, I switched to the pacman package cache directory and ran pacman -U linux-4.0.1... linux-headers-4.0.1... (can't copy and paste from the busted machine, so know that I typed out the full package correctly)
Output:

I figure these are the files created by the install process (built or moved, i dunno). Safe to remove?
I'm about to wipe the machine and start from scratch unless someone says otherwise.

System Hangs after kernel update

Hi Experts,
Client side, they did kernel upgrade in production system . After this upgrade , they are not able to execute any RFCs. Whenever they are executing RFCs , it keep on running continuously (hangs long time).. Not able to get any results.
Please guide me how to handle this problem.
Thanks
Silviya

Hi,
Thanks for your reply.Just forget about kernel upgrade.In my client production, they are trying to execute RFC "RFC_ABAP_INSTALL_AND_RUN",,but the system continuously hanging for one week. They are not able to do anything with RFC. Other ABAP normal programs are working fine.
They creating invoice by RFCs. Whenever they running this RFC , system gets hanging continuously. what may be the reason..and how to correct it .please guide me ASAP. I couldnt get content of sapnote 1151775. If you have sapnote 1151775 details , please give me.
Thanks a lot

Kernel updates kill my luks encrypted system

All right, this is weird. I have a 64bit system with encrypted root, home and swap partitions. To setup I followed the wiki here:
https://wiki.archlinux.org/index.php/LUKS
My swap is encrypted like described here:
https://wiki.archlinux.org/index.php/LU … sk_support
Since the updates to kernel 3.1 each new kernel update kills my system. Pacman says while upgrading

So the generation of the initramfs seems to be ok.
But when I reboot this box, I get:
running hook [openswap]
device /dev/sda4 doesn't exist or access denied
running hook [resume]
waiting 10 seconds for device /dev/mapper/swapDevice
waiting 10 seconds for device /dev/mapper/root
root device /dev/mapper/root doesn't exist. Attempting to create it.
ERROR: unable to determine major/minor number of root device /dev/mapper/root
/dev/sda4 is my swap partition. Then I get dropped to a recovery shell which I can't use because my (usb) keyboard is not working.
Now the funny part. I start the box from a install cd and chroot into the existing installation. I do a
mkinitcpio -p linux
The initramfs is regenerated and it works again! What the hell is pacman doing other than regenerate the initramfs with my presets?

New kernel 3.1.1 did it again. My system hangs in initramfs after the reboot. Same as before: a simple rebuild without any changes fixed the boot process. This time I was able to backup the 'bad' initramfs before chrooting in and rebuilding.
it is very funny to see the content of the 'bad' initramfs image - it is nearly empty!

For some reason the initramfs built by pacman is missing all modules. To say it again, nothing changed, simple rebuilt by mkinitcpio -p linux!
This seems to be a bad bug...

VirtualBox does not start correctly after kernel update

Just recently I have been unable to start VirtualBox after a kernel update. That is to say it seems to be running, but displays nothing.
The following processes are listed: VirtualBox, VBoxSVC, VBoxSVC, VBoxXPCOMPCD
The following modules are loaded: vboxdrv, vboxnetflt, vboxnetadp
Yesterday, when the same thing happened, I reinstalled VirtualBox and it worked correctly again.
I recently upgraded to systemd which has caused me some other problems, so that might have something to do with it
Cheers
Andrew

[kernel] kernel update and third party modules management

Hi all,
I turned to Archlinux with my new thinkpad X220 just for a few days, while I have used Ubuntu for 4 years. I had never controlled my system in such a degree, and feel happy about it.
However, I have a question about kernel update, for I had install some modules from AUR with yaourt( e.g. tp_smapi, acpi_call). For my poor knowledge about pacman, I don't know how to handle those modules while I upgrade my kernel. I cannot remember to re-install all of them!
I think there must be a solution that I didn't found, so I write this thread to ask for help.
Any help would be appreciate.

Mr.Elendig wrote:You can use some silly wrapper around pacman that rebuilds them when there is a kernel update. I'm sure someone has written one already.
Thank you, Mr.Elendig. Do you mean some kind of frontend such as yaourt?
Or some kind of hooks like this:
aur/mkinitcpio-vbox 2.0-3 (Out of Date) (29)
VirtualBox hook for mkinitcpio that rebuilds kernel modules on next reboot
Using the key words you provided, I searched " kernel upgrade module rebuild " and found that gentoo offically provide a tool called "module-rebuild" to reinstall external modules. Maybe it's because gentoo always compile source code? But no other results.
However, now I found what I need to do is just to build the modules listed in the /etc/rc.conf, and that is acceptable. Maybe after a few weeks of study, I can find out my way to solve this problem.
And thanks for your reply.

[SOLVED] Arch - Kernel Update = problem

With the new kernel update when using winetricks to install for instance dotnet20, i always get:
libgcc_s.so.1 must be installed for pthread_cancel to work....
Was working......any ideas to solve this one....
Thanks
PS: STUPID ME, it was missing the multilib lib32-gcc-libs...yeah i know....

So the issue just disappears?? If so I will try this..

The bug report seems to be active, so we will have to wait for a while for the patch... Although there is a proposed patch that seems to remove the UVD error, have you tried it??
I quote a comment "Nopes. It makes the UVD errors go away, but the boot still gets stuck at the same point. Everything hangs up, requiring me to do a hard reboot."
The patch did not fix the bug. Honestly, the bug has been there since kernel 3.11.

Kernel update 3.16.4 unable to boot

Hi everyone,
latest kernel update (yesterday, linux-3.16.4-1-x86_64.pkg.tar.xz) crashed the whole system, i re-installed the old package (linux-3.16.3-1-x86_64.pkg.tar.xz) and i managed to boot up, beyond recovery mod.

Automatically build kernel module after kernel update

Hello. Everytime kernel is updated, my wifi drivers don't work. I need to use this to get my adapter working: https://aur.archlinux.org/packages/8192cu-dkms/ .
After kernel update, I have to manually reinstall the package, so the kernel module gets rebuilt. Is there any way to make it automatic?

I noticed it, but your script doesn't run at all when I type `mkinitcpio -p linux`. And wifi still works after reboot. Same for graphics driver, it has a hook at shutdown, that rebuilds its module after kernel update, it haven't run too and graphics driver works. It's like 'mkinitcpio -p linux' does nothing to the system.

Automatic recompiling of kernel module after kernel update.

Hello everyone,
i tried to search for it but without success...
my question is - is it possible to set it up somehow that aur package would recompile after kernel update?
The package I would like to rebuild is rt3090 which is module for my wifi card. It is very annoying to rebuild it manually. I know that my fglrx module does it automaticaly but how to set it?
Thank all of you for any advise.

Thank you :-) It looks ok, I will try DKMS as soon as I get some free time. If there was any problem, I would tell you.
BTW: I use catalyst mainly because of saving energy management, which is of course better for my netbook. My card is too new to be fully supported by the opensource driver.
EDIT:
I solved the situation by upgrading my system, I tried in-kernel module rt2800pci. In the previous kernels it didn't work well with my crappy ralink rt3090 wifi card, but that's been improved :-) so I do not need rebuild the package anymore even because this module isn't compatible with newest kernel.
I also learnt how to write my own hook from archwiki (https://wiki.archlinux.org/index.php/Mkinitcpio) so if the new module didn't work I would try it.
The final solution = replace module rt3090sta by rt2800pci.
Thanks! Arch has very powerful community :-)

Kernel update crashed boot

Hello,
I've done a full system update Arch doesn't boot any more. The following error message is shown:
ERROR: device `` not found. Skipping fsck.
ERROR: unable to find root device ``
You are being dropped to a recovery shell.
Searching around, I've found that this was a kernel update issue and I should boot from a live CD and do:
# mount /dev/sda8 /mnt
# mount /dev/sda7 /mnt/boot
# mount -t proc /proc /mnt/proc
# mount -t sysfs /sys /mnt/sys
# mount -o bind /dev /mnt/dev
# chroot /mnt /bin/bash
Done that, I should run:
# mkinitcpio -p linux
But this command returns me an error when autodetec hook is reached:
-> Parsing hook: [autodetect]
findmnt: /lib64/libmount.so.1: version `MOUNT_2.20` not found (required by findmnt)
==> ERROR: failed to detec root filesystem
findmnt: /lib64/libmount.so.1: version `MOUNT_2.20` not found (required by findmnt)
And I couldn't solve the problem. Usually I don't post questions because I always find solutions searching, but at this time I've spend half of a day without progress.
Could someone give me a hint, please?
Thanks in advance!

Hi, Gcool
I'm going to check that, latter I post if it worked.
Just an update: I quit trying to solve the findmnt problem and commented out the autodetect option from /etc/mkinitcpio.conf
Once I've done that, mkinitcpio runned just fine, but unfortunately the problem is still unsolved.
The complete output error from boot is:

[SOLVED] no timidity service + pulse, kernel update (3.16.3-1)

I had sound working before upon boot, but sound was failing after resume from suspend on HP dv7 laptop. I hadn't gotten around to figuring out how to store alsa state (what I believe to be the solution to sound failing after suspend). My install is about a week old. I ran pacman -Syu to get into the habit of doing so. Now I know why it is suggested to not do the updates when you don't have time to fix things that might need to be fixed.
alsamixer is not muted, but I only see master channel as user or root - selecting the Intel PCH sound card within alsamixer allowed me to see the other channels, but speaker-test remained silent. But I have been consistently seeing PCH Transcoder A errors on boot. Wasn't sure what they were, since everything had worked prior to kernel update. Investigating sound yields my hardware is Intel PCH, so these errors may be important, but I am also unsure how to access any log they might be recorded in.
EDIT: speaker-test and timidity work in single user console mode, but not in KDE.

I discovered sound did not work after rebooting to restart sound for Rosegarden. Rosegarden was still open when I started running these diagnostics. speaker-test does not work either. The above fuser command returned nothing after closing Rosegarden, but speaker-test remained silent.

Any ideas on what I should do? Also, why did my sound break, and what should I do to prevent sound from breaking in future kernel updates?

fluidsynth (needed for Rosegarden) has been told to use pulseaudio instead of alsa directly (as per https://bbs.archlinux.org/viewtopic.php?id=154002 )
What worked to get speaker-test running in Konsole: adding -D to:
ExecStart=/usr/bin/timidity -iA
to become
ExecStart=/usr/bin/timidity -iAD
in /usr/lib/systemd/system/timidity.service (as per: https://bbs.archlinux.org/viewtopic.php?id=149339&p=2 post 29)
Additionally, I was able to see a default audio device in KDE system settings...multimedia instead of just dummy device. However, even after preferring the default audio device for everything (and it tests fine), Rosegarden still has no volume. Timidity in Konsole plays audibly now too. I am now going to reboot and see what the status is.

SAP ECC 6.0 IDES KERNEL Update

Dear experts,
i have installed a SAP ECC 6.0 IDES on a Windows Server 2003 Enterprise 64 bits + MS SQL from the MarketPlace:
-> http://service.sap.com/swdc
-> Download
-> Installations and Upgrades
-> My Company's Application Components
-> SAP ERP
-> SAP ERP 6.0
-> IDES-Version
-> Windows Server
-> Microsoft SQL-Server
and in order to update my solution into EHP3, i need to update the Kernel witch is in 7.00 version.
How and Where could i get the kernel update file?
Is there any difference between SAP Netweaver and SAP ERP Installation?
Thank you very much for your great help.
Best regards,
Pascal.
PS: i already update the SPAM/SAINT version (number 33) and have a well configured MOPZ for confirmed files.

Hello Pascal,
The kernel is at a differnt location. Please go to:
1. http://service.sap.com/swdc
2. Download
3. Support Packages and Patches
4. Entry by Application Group
5. Additional Components
6. SAP Kernel
Select the corresponding platform.
You should download 2 kernel files: SAPEXE and SAPEXEDB. One is database independent, one is DB dependent. Unpack them to the kernel directory and the kernel then is upgraded.
Best Regards,
Joseph

Problems with key shortcuts after kernel update (can't shutdown wifi)

Hi! Sorry for my poor english!
I have 2 problems on my laptop that went out after a kernel update; the first one involves the wireless card (Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01), but I don't think it is important): when I press the key shortcut it switches off only partially, the led remains lighted and with "rfkill list all" i get that is actually only software blocked.
The second problem is about the key shortcut to switch off the screen: even with xev it isn't recognised anymore.
I am pretty sure the 2 problems are related; the latest kernel with they were working is 3.5.6-1, in fact if I downgrade to that version I haven't got any problem.
I have encountered this issue with 3 models of Asus EEEPC: 1015pd (mine), 1215b and 1015cx, (the first two with AR9285, the third with AR9485).
Thanks for the help ;-)

Ok, so after removing catalyst-test and trying to install catalyst, I got the following error:
resolving dependencies...
warning: cannot resolve "catalyst-utils", a dependency of "catalyst"
:: The following package cannot be upgraded due to unresolvable dependencies:
catalyst
Proceeding to try installing catalyst-utils...

No sound after (kernel)update 64bit

Hey I just rebooted my PC the first time after the new kernel update.
Now sound is not working anymore at all... But the soundcard (Audigy 2 ZS) is still recognized (e.g. via alsamixer), and kmix does not give any error message. Everything seems to work fine, except the fact that there is no sound. Of course I already checked if I muted anything by mistake. Sound is working on Vista (dualboot), so the hardware is alright.
Any hint what could be the problem?
PS: I stressed the kernel update in the first line, because I strongly suspect it for being the cause of the problem. The other updates were not that important (samba...).
But I would like to hear other opinions.
Greetings, yodo
Edit: Ok, I manually compiled and installed an older kernel (kernel26-2.6.27.8-1) and sound is working again. It was definitly the kernel's fault! The version(s) I had (have) problems with were kernel26-2.6.27.10-1 and also kernel26-2.6.27.9-1 which I tried before kernel26-2.6.27.8-1.
Any other users with the same problem?

Thanks! But actually rebuilding the kernel did not fix anything (for me) - at least not rebuilding kernel26-2.6.27.10-1 or kernel26-2.6.27.9-1. Sound only works after a downgrade to kernel26-2.6.27.8-1 (or below I suppose).

Mounting issues after kernel update (2.6.25)

After installing the recent kernel update, mounting has gone haywire. When I put in a cd (in either of my 2 drives) it doesn't mount. In thunar, when I click on the cd drive, it displays this error:
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
I did dmesg | tail and I got this:
EXT3-fs: mounted filesystem with ordered data mode.

UDF-fs: No VRS found
Also, when booting a few minutes ago, it was stuck on the "checking filesystems" for a few minutes, when it usually does that step almost immediately. I also couldn't mount an iso, this is what happened:
[root@eric-arch eric]# mount -o loop -t iso9660 /path/to/iso.iso /mnt/iso2
mount: could not find any device /dev/loop#
Note: I am not certain that it was caused by the kernel update, but that is the only thing I did to my machine before this started happening.
Please help asap because I need to do schoolwork which is on a cd.

That worked, but I still have other issues with cd mounting, so I downgraded my kernel for now.
