[SOLVED]pc freezes after resuming from suspend.

When I upgraded kernel from linux-3.3.8-1 to linux-3.4.2-2 or later , PC freezes after resuming.
Monitor comes back and kde requires passward , but after few seconds , everything freezes.
keyboard and mouse won't respond.
There is no log after resuming.
Is there anybody who have same trouble?

In my case, monitor freezes too.
And I have only one PC, so i can't try ssh.
I logged into runlevel3 and try
sudo pm-suspend
and it works fine. So it seems this trouble caused only in runlevel5.
I also tried following command in runlevel5
# echo freezer > /sys/power/pm_test
# echo mem > /sys/power/state
# echo devices > /sys/power/pm_test
# echo mem > /sys/power/state
# echo platform > /sys/power/pm_test
# echo mem > /sys/power/state
# echo processors > /sys/power/pm_test
# echo mem > /sys/power/state
# echo core > /sys/power/pm_test
# echo mem > /sys/power/state
Everything works fine but sudo pm-suspend failed.

System freeze after resume from suspend

I am running arch for about 5 month now and I always had freezes after resuming from suspend (to ram - systemctl suspend) every once in a while (like once a week or less). The freezes increased massively over the last month or so and for about 2 weeks now it happens 95% of the times I resume from suspend.
The monitor turns on and shows things exactly how I left them, but is completely unresponsible EXCEPT for I can switch to another TTY (Ctrl+Shift+F*), however I cannot type or do anything in it...
It doesnt have anything to do with the X server as it also happens after I suspend from TTY (without any X running).
I also checked journalctl -b -1 (shows previous boot, since I always have to hard-reset the system) but it doesnt show anything after:
Mar 13 17:16:54 Ununhaswellium systemd-sleep[3624]: Suspending system...
(the suspend event before resuming)
Are there any log files that could give a hint on what exactly goes on after the resume?
Im running the latest official 3.13.6-1 kernel and updated my BIOS to the latest beta version yesterday - didnt help either...
Ive read pretty much every thread on the internet by now about freezes after resume from suspend but none really helped

Thank you for the link, unfortunally I don't have a NVIDIA card but use the Intel IGP (HD4600, Haswell) - maybe I should have mentioned that...
And other than in this bug report I cannot kill X or anything because neither other TTYs work - I cannot input anything (although the hotkeys work weird enough) nor is SSHD running because the system is completely frozen...
Very funny thing is that for the last 2 days my system didnt freeze once (suspended about 6-7 times during one boot), even though for the 2 weeks prior to that, it froze EVERY SINGLE TIME I resumed from suspend, it didnt work once...

System freeze after resume from suspend to RAM

Hi,
since quite a while (probably ever) I am unable to suspend my computer to RAM because everytime it freezes a few seconds after resuming, never to become alive again until a reboot. After some investigation, I managed to get kernel logs by taking a picture of my screen. The logs were not written to disk, hence I didn't see anything before. I had to write these by hand, I hope I didn't insert any mistakes:

This issue seems to be related to disk failures like bad sectors but I am quite sure, that my SSDs are in a good shape. I ran some SMART tests, they all turned out to be okay. Suspending from my dual-booted Windows works fine as well (although if the bad sector would be on the linux partition, it would probably not affect Windows).
Here's my setup:

I am not sure which one of the disks causes the freeze but I assume it's the revodrive because the logs talk about two drives. The Revodrive internally holds two drives, which are set up to operate in a RAID 0. Windows is installed on the Corsair drive, and has no access to the Revodrive. However, I used to run Windows on the Revodrive a few years ago, and it worked just fine.
Another interesting thing is that when I try to test suspend to RAM, the system does not freeze, nor produce errors. This only happens if none is written to /sys/power/pm_test (which means no automated wake-up, no testing).
Any ideas on how I could narrow down this issue? Thanks a lot!
EDIT
I just checked and confirmed that this issue is originating from the OCZ Revodrive:

[SOLVED]No sound after resuming from suspend thinkpad t23

On a T23 Thinkpad, suspend-to-ram works, but I have no sound and no network when resuming.
After googling for a while, it seems I must unload sound modules before going to sleep and then reload my sound modules after resuming.
lsmod|grep snd gives me this:
snd_intel8x0 28700 3
snd_ac97_codec 94756 1 snd_intel8x0
snd_pcm_oss 38432 0
snd_pcm 68996 3 snd_intel8x0,snd_ac97_codec,snd_pcm_oss
snd_timer 19332 1 snd_pcm
snd_page_alloc 8072 2 snd_intel8x0,snd_pcm
snd_mixer_oss 14464 1 snd_pcm_oss
snd 44388 12 snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_pcm,snd_timer,snd_mixer_oss
soundcore 6496 1 snd
ac97_bus 2432 1 snd_ac97_codec
However, from the command line, after
modprobe -r snd_seq_oss snd_seq snd_seq_device snd_intel8x0 snd_ac97_codec snd_pcm_oss snd_pcm snd_timer snd_mixer_oss
I get:
FATAL: Module snd_intel8x0 is in use.
Even though I have no sound apps running.
I am planning on putting the modprobe -r command in /etc/pm/sleep.d/whatever to unload and then another to reload the mods.
Any help appreciated.

OK, solved it. Placed this in /etc/pm/sleep.d/11suspend
#!/bin/sh
mixers="Master PCM CD"
for mixer in $mixers ; do
/usr/bin/amixer -q sset $mixer mute
/usr/bin/amixer -q sset $mixer unmute
done
Just mutes and unmutes master, PCM and cd channels. Works perfectly. suspend-to-ram and hibernate now work 100%.
Thinkpads are so sweet.

[Solved] No sound after resuming from suspend

After suspending and resuming I no longer have any sound output (through headphone jack or my laptop speaker). The laptop is a toshiba portege r835. I can't say how long this has been happening, since I've only tried to play any sounds after resuming recently.
Searching the forums I found the following thread: https://bbs.archlinux.org/viewtopic.php?id=151001
I haven't tried this because it isn't exactly the same problem, but mostly because I'm currently stuck on kernel 3.5.6 because of the sandy bridge power regression issues.
Does anyone have any other ideas on how to possibly fix this problem?
Thanks!!

Solved, sort of.
I had some double suspend issue: I had set up suspend with systemd before using xfce and then after installing xfce I set my power settings so that the computer would suspend after shutting the lid, so I would have to open the lid, shut it, and then open it again for the computer to actually resume. After turning off the suspend setting in the xfce power manager, and just using the systemd suspend, the sound works fine on resume (both headphones and speakers)!

Touchpad permanently not working after resuming from suspend

I lost touchpad and trackpoint functionality after resuming from suspend on my ThinkPad E530 (3259CTO).
Even after a complete power off (with the battery removed), the touchpad is detected but doesn't send any event, and the trackpoint is not detected.
In Windows, in the UltraNav control panel, the touchpad is marked as enabled and cannot be disabled, the trackpoint is grayed.
In Linux, I can see the difference is kernel traces when the driver is loaded.
Before : psmouse serio1: synaptics: Touchpad model: 1, fw: 8.0, id: 0x1e2b1, caps: 0xd001a3/0x940300/0x120c00
Now : psmouse serio1: synaptics: Touchpad model: 1, fw: 8.0, id: 0x1e2b1, caps: 0xd001a3/0x0/0x0
After looking at https://gerrit.chromium.org/gerrit/#/c/31105/ and Synaptics public documentation, I was able to get more information : the device status register (F01_RMI_Data0) is 0x45, which means the touchpad is in flash programming mode since there is a firmware CRC failure.
It looks like http://code.google.com/p/chromium-os/issues/detail?id=24298, so it's probably not a Lenovo specific problem, but a bug in Synaptics firmware.
Can Lenovo provide the firmware to flash like http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/X220-Touchpad-jumpy-response-when-used-with-90... which would hopefully make my touchpad working again ?
The original firmware should work, but an updated one would be better, if it avoids losing the touchpad again later.

I don't know why, but this made me think of the episode of the simpsons when home tries to get over 300 pounds so he can work from home. When he tries to dial the phone he hist all the buttons and gets a recording that says "We're sorry, you're fingers are too fat. To obtain a special dialing wand, please mash the keypad now."
BTW, sorry I can't help... but at least I am entertained easily.

No sound in Flash after resuming from suspend

After I resume from a suspend or sleep there is no sound in Flash and there is no networking.
The only way is to restart my browser to reestablish the sound.
Is there a solution for this problem?
Thanks.

This does not happen with Firefox in Ubuntu, as an example. So something must be wrong somewhere.
I can confirm this happens to me in Arch with Firefox 4.0b7 and Chromium 7.0.517.44. I noticed that after resuming from suspend, not only sound (in Flash) is missing, but Flash is behaving weirdly (YouTube video plays much faster) and CPU usage goes crazy without doing any particular action.

Cannot connect to X server after resume from suspend

Hello,
i'm a happy user of arch and i3, one and only thing that is not working correctly is that sometimes after resume from sleep (closing the lid, and then opening) I am not able to start any programs. this happens about 50% of the time. when it happens i have to exit i3 and login again, and everything works ok then.
I'd be grateful for any suggestion how can I debug and solve this problem.

the error was, after running xterm:

after running scrot
No protocol specified
giblib error: Can't open X display. It *is* running, yeah?
after running firefox

but I think I was able to fix the problem.
when I was browsing the internet for solution, I stumbled upon an info about similar problem caused by the hostname set to localhost. I checked my system, and apparently I haven't set my host name during install, and it was still localhost, so I changed it. and after that I tried suspending several times, and the problem never occured. I'll test in upcoming days, and if it works I will change the thread title to [SOLVED].

Dell Inspiron 7537 - Sound only works after resuming from suspend

Hello,
So my sound does not work after boot, only once I resume from suspend. So, once I turn on my computer, and I load sound, nothing work (everything is unmuted in Alsa) - then if I suspend my computer and resume - the sound works every time.
I use Alsa and here is my amixer output (before and after suspend is the same) :
eric@archlinux ~> amixer

What gets rebooted when I do a suspend, but not when I reboot? Does not seem to make sense to me.
Thanks.

Is there any additional information I can include to help figure this out?

Desktop visible after resume (from suspend) and before screen is locke

My desktop becomes visible for brief period (<1s) when the system resumes from suspended state. My desktop env. is XFCE4, it happens with both xscreensaver and gnome-screensaver (also with slimlock and i3lock), therefore I think it's not locker dependent. It's a major security flaw because sensitive information may be exposed (not just porn). Using both XFCE provided locking facilities (suspend/resume lock options in Power Manager and Session settings), and systemd suspend/resume hooks yields same result. I remember back then when I was using Gnome, I haven't had this issues. Does anyone have any idea how to prevent this desktop expose?

Using 10.0.r42, iceweael and linux 2.6.32 kernel.
If I close the lid on my HP laptop which causes it to suspend, and the resume from suspend, other audio playing programs work, but I cant get any sound from iceweasel/flash until I kill all instances of iceweasel and restart the web browser.
Is this a bug that is tied to flash?

What a coincidence, mine is also from scratch.
Good question about how sound is handled. ldd libflashplayer.so doen't give an answer.
So somehow xulrunner can catch the sound.
Libxpcom is linked to libasound. components/libmozgnome.so to libesd in my case.
Maybe you can try fuser /dev/snd/* to identify which process is locking the device.

[SOLVED] After resume from suspend to RAM, system is slow / unstable

Hello,
I have come across some strangeness when trying to suspend my system. The
computer is a lenovo U350. I have read a lot of threads on these subjects,
but I never found one that quite matched the experiences I'm having, so I felt
compelled to make a new post.
Here's what's going on: I boot into the terminal, and then run pm-suspend.
Within a few seconds, the computer goes to sleep, just as I had hoped. The
problem is that my computer seems a little groggy when I wake it back up.
Usually, when running a command like ps aux | less, the screen fills up very
quickly. After I resume from sleep, running ps aux | less is noticeably slow.
It takes a full second (+/- epsilon) to fill the screen. Other symptoms: if I
suspend / resume in the terminal, and then start a window manager (KDE), the
graphics will be slow and choppy, and when I try to exit the window manager, I
usually end up having to perform the dreaded REISUB after getting stuck on a
blank screen with a non-blinking cursor in the upper left hand corner.
Suspend / resume from KDE will result in either the black, non-responsive
screen as soon as I try to resume, or in the choppy graphics, followed by the
non-responsive black screen when I log out.
I looked at the process list before and after, and noticed that when the
system is first resumed, there are around 50-60 additional kworker processes
running than when I put it to sleep. I don't know if this is normal or not.
Also, hci0 has been killed, and a new hci0 process has taken its place. The
same goes for one of the udevd processes. About 40-50 of the kworker
processes finish after a few minutes, but this does not change the slowness of
ps aux | less, nor does it help with my window manager issues.
I ran a few (not so precise) performance tests before and after doing a
suspend, and got the same results (the test was just to compile some LaTeX,
which took about 4-5 seconds either way).
I examined the pm-suspend.log, and everything looked peachy. All of the
hooks returned success for the suspend, as well as the resume. I'm happy to
post this if needed. I did not change any of the default settings for
pm-suspend.
Anyhow, I've read a lot of threads, and seen a lot of suggestions, e.g.:
https://bbs.archlinux.org/viewtopic.php?id=137682
https://bbs.archlinux.org/viewtopic.php?id=136292 (use vbetool?)
https://bbs.archlinux.org/viewtopic.php?id=126174 (suspend tons of modules?)
https://bbs.archlinux.org/viewtopic.php?id=131827 (hpet=disable ?)
However, I'm not that confident in any of them, since no one had quite the
same issue. I was hoping that someone could point me in the right direction
before I start blindly walking through all the candidate fixes and risk
unleashing chaos into my system. Many thanks in advance for your help.

I did try reinstalling, actually. But I did not think to remove the battery and the ram... I'm very curious now: what is the rationale / intuition for that? Or is it just that empirical evidence suggests this may be a good idea?
Anyhow, the reinstall by itself did not help. I tried it out with a pretty bare-bones setup and had the same results. Here are a few other things I noticed:
- After the suspend, one of the cores is always running at the maximum clock frequency, according to powertop (although, according to ps aux, no one is doing any work).
- Even if I ssh to a nearby machine, I get the same experience when running `ls`. The screen fills very slowly. That narrows things down a little bit, but I was already guessing it would be graphics-related.
I have also tried a few random kernel boot parameters after reading things online, but none of those worked, and several stopped the machine from booting at all.
Thanks for your help.

[SOLVED] black screen when resuming from suspend

Hi all,
I've got this new laptop and I can't get it to resume from sleep. The screen is black, probably not even powered. When I resume I am still logged into my session and can type commands (espeak for example, which works), and I can use my other computer to ssh and get the logs.
This new computer has got hybrid graphics card from AMD. I think this is relevant, as I've read some stuff about the GPU not being powered after sleep.
$ lspci
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Richland [Radeon HD 8650G]
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Neptune XT [Radeon HD 8970M] (rev ff)
I'm using the open source drivers because I'd like to use bumblebee to switch between graphic cards. It's not working yet, though.
Also I've read some topics concerning similar issues, but most of them were solved by upgrading to a newer kernel, like 3.8 or 3.9 at that time. I am running 3.16.7 (these topics were from 2013, I found nothing more recent).
To suspend, I close the lid of the computer or use
systemctl suspend
I tried switching to pm-utils for suspend and resume, it still didn't work, event with all the troubleshooting tips on the wiki.
I'd be glad to provide any logs you would need in order to help me.
Thank you for your help
EDIT: I forgot to mention that the brightness keys work well before suspend but have no effect afterwards.

I found this post, but I don't know if this is relevant or not.
It says:
ps: if you use this method, before suspending or hybernating make sure that the intel card is the one in use, or when you recover the pc the display won't show anything (or at least that's how it work on my laptop)
It is about AMD/Intel hybrid graphics with vga switcheroo, and I'm on AMD/AMD and not using switcheroo, but I don't know enough to say if this is the same problem or not.

[Solved]netcfg2 behavior on resume from suspend

I'm using the core/netcfg package to manage wireless with my HP DV6000 laptop (b43 driver for Broadcom 4311 card). I have two profiles setup - one for home with a WPA network and one for work with an unencrypted network. At home, I can suspend (using s2ram from the uswsusp pkg) and resume, and the wireless will automatically reconnect on resume.
At work, on the unencrypted network, I don't get the wireless back on resume. Ifconfig and iwconfig show the ip address and that the connection is still up, but I can't even ping the router. In order to get it back, I have to do netcfg2 -a && netcfg2 station1.
Any ideas why this might be different?
Here are the two profiles:
CONNECTION="wireless"
DESCRIPTION="Home"
INTERFACE=wlan0
HOSTNAME=scotty
IP="dhcp"
ESSID=homeessid
SECURITY=wpa # One of wep, wpa, wpa-config, none
KEY="secretkey"
SCAN="YES"
TIMEOUT=10
CONNECTION="wireless"
DESCRIPTION="Station 1"
INTERFACE=wlan0
HOSTNAME=scotty
IP="dhcp"
ESSID=dd-wrt
SECURITY=none # One of wep, wpa, wpa-config, none
SCAN="YES"
TIMEOUT=10
[Thanks, Scott

Oops . . . sorry Profjim .... didn't see your post before I bumped! The dhcpcd commands don't seem to work after a resume.
However -- I figured out how to make it work -- not sure WHY, but it works!
I had added the 's2ram -f' command to /etc/acpi/handler.sh under the lid/button event to trigger the suspend (since pm-suspend would freeze on resume). BUT -- after adding /etc/pm/config.d/config with:
SLEEP_MODULE=uswsusp
ADD_PARAMETERS="--force"
in order to force pm-suspend to use the uswsusp suspend (which works properly for my hp dv6000), AND change the 's2ram -f' to 'pm-suspend' in /etc/acpi/handler.sh -- it WORKS! Ok -- well, the resume at work on the unencrypted network works now to restore the connection. Still have to check it at home on Sun.
Thanks all!

Keyboard Very Glitchy + Speakers Clicking After Resume From Suspend

Hello,
Didn't know exactly where to post this, so I chose newbie. I have a very strange issue regarding suspending and resuming on my Arch64 box. When I resume from a suspend, everything seems to work okay, however first I hear this from my speakers:
*pop* [pause] *pop*
And then, when I use the keyboard, it responds very strangely. Every key still types what it should, but letters will be frequently either skipped over to carried out longer.
Here's a good example:
If I type this before a suspend: "Arch Linux rules!"
It may come out like this after the suspend: "ArcLinux ruuuuuuuuul!"
See what's happening?
So when this happens I must reboot, and then it works fine again.
My machine is an HP Pavilion DV7 6199us running on Intel graphics (sna acceleration) with the Radeon card disabled with acpi_call.

Please inform me of any more info you would need.
This is pretty confusing, any help highly appreciated, thanks!

I have found a workaround in this bug report.
Make a script in /usr/lib/systemd/system-sleep/keyboard.sh
#!/bin/sh
case $1/$2 in
post/*)
echo -n rescan > /sys/devices/platform/i8042/serio1/drvctl
esac
Do not forget to make it executable:
chmod a+x /usr/lib/systemd/system-sleep/keyboard.sh

[SOLVED]pc freezes after resuming from suspend.
