Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

Another piece of news and info. I just noticed that if I connect a 3GS iPhone to my computer, sometimes upowerd segfaults:

Aug  3 18:23:54 localhost kernel: [  280.471777] upowerd[3078]: segfault at 0 ip 00007f0fa4cbe5b0 sp 00007fff80ddf538 error 4 in libc-2.16.so[7f0fa4bc8000+19b000]

(This is even worse if I boot with the phone connected).

But that's not important. What is important is that when upowerd is not running, the computer will not suspend by closing the lid but will still suspend with the pm-suspend command. I really think we should be looking into upower, too!

I will downgrade upower and report back!

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

hmmm, I do have an ipod touch that I occasionally (but very rarely) charge on the laptop. This would explain why this happens to me so much less than to the other people in this thread!

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

Unfortunately, I downgraded upower to 0.9.10 and the same thing happened again after 25 hours of uptime :-(

I am really out of ideas. The only thing I can think of next is to install a *new* system from scratch on the same laptop and see what happens. If it happens on the new install, bummer. If it doesn't, start converting the new system to the configuration of this one. But this will take time, something I don't have. Anyone willing to try this kind of thing on his/her machine?

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

I think what I'm going to try is just buying a plug charger for my ipod, and see if that fixes it. I tried plugging it in again to see if it would trigger the thing, and it didn't, but it did happen again the day after that. So to me it seems like it is indeed the idevices at fault. Maybe installing libimobiledevices could help as well.

No, no. At most, an idevice will crash upowerd and then your laptop won't suspend by closing the lid....

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

yeah, but I figured that may have been the reason. Well looks like I jinxed it anyway, it happened again to me today.

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

And it happened again while on Gnome 3.4. The desktop environment does not have anything to do with it. Something is happening on closing the lid. This is what we should track.

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

Ok, I've tried something else. Let's see if this helps.

I've disabled suspending on lid-close from XFCE power manager (and tested it, nothing happened). Then installed acpid and edited /etc/acpi/handler.sh to execute pm-suspend in lid close event. Also, I've set SUSPEND_MODULES to

SUSPEND_MODULES="iwlwifi uhci_hcd ehci_hcd button sdhci sdhci_pci mmc_block mmc_core"

Fingers crossed.

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

Hi, I'm not sure if we have exactly the same problem, but it could be. I'm also using a Lenovo (Z575) and am having trouble waking up from suspend:

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

Ok, it happened again... No matter what I try, the problem persists. But I can confirm that no weird ACPI events get sent since I was logging them and only saw this:

Wed Aug  8 11:57:40 EEST 2012: button/lid LID close
Wed Aug  8 12:00:25 EEST 2012: button/lid LID open
Wed Aug  8 12:02:50 EEST 2012: button/volumedown VOLDN 00000080 00000000 K
Wed Aug  8 12:13:48 EEST 2012: button/lid LID close

And after that, no more ACPI events get registered.

Compare the /var/log/everything.log

As you can see, up to these:

Aug  8 12:13:49 localhost kernel: [18574.990237] PM: Preparing system for mem sleep

they are completely identical. After that, we see that on the failed suspend, X crashes:

Aug  8 12:13:49 localhost kdm[14167]: X server for display :0 terminated unexpectedly

and the kernel never states

Aug  8 12:00:24 localhost kernel: [17769.397967] Freezing user space processes ... (elapsed 0.01 seconds) done.
Aug  8 12:00:24 localhost kernel: [17769.411209] Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done.
Aug  8 12:00:24 localhost kernel: [17769.424542] PM: Entering mem sleep

as it always does on a successful suspend.

On a side note there is this rtkit-daemon stating the wrong time, but this normal behaviour as it runs in its own chroot environment and has no access to localtime. (At least that's what they say).

So after all this tampering and fiddling, I am back to where I started. The kernel just *STOPS* the suspend process in the middle, no errors reported apart from X crashing and I'm left in the dark. I weep.

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

Another piece of news and info. I just noticed that if I connect a 3GS iPhone to my computer, sometimes upowerd segfaults:

Aug  3 18:23:54 localhost kernel: [  280.471777] upowerd[3078]: segfault at 0 ip 00007f0fa4cbe5b0 sp 00007fff80ddf538 error 4 in libc-2.16.so[7f0fa4bc8000+19b000]

It's maybe a bit off-topic but: Have you found out how to prevent this? I get the same error and because of this I am unable to copy music to my iPod touch.

No, I haven't :-( ...  I transfer files to and from my jailbroken iPhone using SSH...

On our problem, I've tried booting with i915.semaphores=1 kernel parameter and see what happens. I've got the impression that the only thing I haven't tried is downgrade X and/or intel KMS driver so it may be related to that.....

By the way, are we all using the i915 kernel driver?

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

oh yeah, I should mention that this doesn't happen to me with my ipod touch. upowerd has never segfaulted either according to my kernel.log. I don't have libimobiledevices installed though.

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

No deal, i915.semaphores and it happened again. Nothing suspicious in acpi events, /var/log/everything.log contains exactly the same sequence! The suspend procedure stops at "preparing system for mem sleep" and X crashing....

WTF is going on!?!?!?!?!?

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

Have you tried setting SUSPEND_MODULES="thinkpad_acpi" in /etc/pm/config.d/modules? I had a similar problem on my W520 with occasional hangs when resuming, and this change seems to have alleviated it for me (or, at least I haven't experienced the problem in a couple weeks...).

There was some information at the Thinkpad wiki at http://www.thinkwiki.org/wiki/Thinkpad-acpi, although their server appears to be down right now.

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

I am now at 29 hours of uptime and it hasn't happened. There are 3 things that have happened.

-> The xf86-video-intel driver has been updated about 12 hours ago
-> I killed the X server to reload the new driver (by running init 3 and then again init 5 as root)
-> I am using acpid only and having it run a test pm-suspend before the actual one:
(excerpt from /etc/acpi/handler.sh)

logger 'LID closed'
LOG=/var/log/suspend-debug.log
echo "     " >> $LOG
echo " ----- SUSPEND: `date` ----- " >> $LOG
echo "     " >> $LOG
dmesg -C
echo "--- Testing Core ---" >> $LOG
echo "core" > /sys/power/pm_test
pm-suspend
dmesg >> $LOG
dmesg -C
echo "--- Actual suspend ---" >> $LOG
echo "none" > /sys/power/pm_test
pm-suspend
dmesg >> $LOG
dmesg -C
;;

I have not reached 29 hours of uptime with suspend/resume cycles before. This tells me that something of those 3 affected the issue. It could be that it was xf86-video-intel's bug and now it's fixed (unlikely, but then again, why not?), it could be that this was (and still is) an X issue which happens after continuous use of X (and by killing it, I managed to reset the "bug counter") or somehow setting "core" to pm_test, trying a test suspend and then "none" and actually suspend bypassed the issue somehow.

If it is fixed in xf86-video-intel, I should be able to go on without any problems.
If it is an X issue and the bug counter was reset, I should have the problem appear at about 36 hours.
If it is the test suspend, I should be able to go on without problems.

OR, it could be that nothing has affected the issue and it is a coincidence. We'll soon find out, one way or the other.

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

Ha. So it happened again just now. 34 hours of uptime.

This leads me to believe that it is directly connected to X. Further, this seems to be connected to X's uptime.

But a new version of X just came out, maybe this is fixed?

Fingers crossed (again!)

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

The same happened again with the newer 1.12.3.901-1 xorg-server.

I'll try to confirm by killing the x server every now and then, see if I can get some uptime this way.

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

It is one hell of an annoying bug. It appears on a lot of systems (read about it on gentoo, debian, ubuntu and arch fora). Nobody seems to have a clue.

My summary (as a report of negative results):

On ubuntu 11.10 all worked well for me; I upgraded to 12.04 and the problem emerged.
-I installed arch from scratch (using the July 2012 code) with plain vanilla openbox and it happened again: every now and then after awaking after suspend X crashes for no reason.
- i tried uninstalling acpid and invoking pm-suspend: no effect
- i tried the lts kernel: no effect and the sporadic crashes persist.
- Downgraded to the previous Xserver, no effect.

Currently running a 3.0.4 kernel with thinpad_acpi, hdaps and thinkpad_ec modules: still no effect. X keeps on crashing every now and then after suspending.

I'm kind of desperate because I use my laptop for work and I rather suspend then shutdown-boot every time as i can leave my files open where I finished. Going back to an old ubuntu version is probably not the way forward as i need some "new" software packages.

Anybody any clue?

(btw, shall we try to bundle all forum posts about this issues. There are at least a few other already on the arch forum: here, here)

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

I just noticed these two lines on my clean/after-boot dmesg:

[    0.363136] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored
and
[    0.387856] PCI: Using host bridge windows from ACPI; if necessary, use "pci=nocrs" and report a bug

Anyone else has these?

Yes, I do have both of these in my dmesg:

[    0.405755] PCI: Using host bridge windows from ACPI; if necessary, use "pci=nocrs" and report a bug

Re: [SOLVED]Linux3.4 broke resume/suspend some of the times in Lenovo T420

Well, it certainly is Xorg (at least partially) to blame. I am now at 60 hours of uptime with proper suspend/resume cycles by closing the lid.

The way I have done this is by killing the X server every 10-12 hours. Not a "solution" but at least we can start looking somewhere... I'll file a bug and see where it goes from there...

By the way, is anyone here experiencing the issue NOT using the i915 kernel driver? (i.e. non-intel graphics?)
