Description Jithin Emmanuel 2010-01-09 16:48:23 UTC
Hi there,
With the 2.6.32 kernel the laptop screen just goes blank. I initially thought it was when laptop lid is closed and opened. But I was hit with this even with out that by just staying idle. Even with lid close there is no reliable way with which I am able to reproduce this. It appears to occur randomly. 

But they leave a stack trace in the logs

Comment 1 Jithin Emmanuel 2010-01-09 16:50:23 UTC
Ther problem was not present in 2.6.31 kernel.
Comment 2 Jithin Emmanuel 2010-01-21 01:26:36 UTC
With kerner 2.6.32-4 the problem still exists.
But its a different stack trace.

If you have noticed the time, I closed the laptop lid at around Jan 20 12:30 PM and freeze occurred at Jan 21 05:52 AM.
Comment 4 Johannes Engel 2010-01-21 12:21:43 UTC
Is this maybe related to #14933?
Comment 5 Jesse Barnes 2010-01-25 18:40:08 UTC
Yakui, looks like our DPMS on or off path is spinning forever somewhere?  Any ideas?

Comment 8 Jithin Emmanuel 2010-01-26 01:57:45 UTC
I am using 2.6.32.5 kernel at the moment. So far I have not seen this issue with this kernel version. But considering the random nature I would like to wait a day or 2 to confirm.
Comment 9 Jithin Emmanuel 2010-01-26 04:09:50 UTC
I spoke too early. I got my first blank screen in days and with kernel 2.6.32-5
The laptop was just in a locked state lid was not even closed.

Log is same as that of one in description

Comment 10 Jithin Emmanuel 2010-01-30 12:07:11 UTC
I am now with 2.6.32-6 kernel and the problem is still there. I just cannot leave my laptop idle, it will freeze fore sure.
I am also facing a system freeze during shutdown sometimes. Its totally broken atleast for me.
Comment 11 Ivan Bulatovic 2010-02-01 09:17:33 UTC
That bug with softlockup going endlessly is fixed with 2.6.32.7 (at least for me), what is strange about it that there were no drm/i915 fixes from 2.6.32.6 and browsing to the changelog I couldn't find anything relevant to this kind of behaviour.

However with 2.6.33-rc5 this bug is still present, at first I thought it was because of LVDS downclock feature but I'm not so sure anymore.
Comment 12 Jithin Emmanuel 2010-02-01 09:19:07 UTC
I installed 2.6.32-7 today. Will monitor for a couple of days and report back if its fixed or not.
Comment 13 Jithin Emmanuel 2010-02-02 03:34:28 UTC
I can confirm that this bug is not fixed with kernel 2.6.32-7. Just now I had a blank screen. The laptop lid was closed and I was away for about 1 hr.

I had the same soft lockup logs in /var/log/kernel.log and had to do RSEIUB.
Comment 14 Jithin Emmanuel 2010-02-02 03:40:47 UTC
Strange that I did not face this bug when I was using it at home and was easily reproducible at office. I use a docking station with my laptop at office. Could that trigger the issue.
Comment 15 Jithin Emmanuel 2010-02-03 01:54:33 UTC
This is happening every where. NO connection to using docking station. It froze twice yesterday. My system was doing a massive update to kde 4.4 rc3 and some whee in middle it froze. It was 2nd time at home. Printing the same soft bug lock up bugs. 
2.6.32 kernel is totally broke. IT also froze just 5 mins earlier when I was doing VT switch. I dont know when I did some 10-15 switches and it froze after that.

This 2.6.32 is a great release.
It freezes when,
1. sitting idle.
2. doing vt switch
3. suspend
4. restart/shutdown 
and all random. Great job!! and no one is even looking in to this one. Atleast the suspend one I reported is getting enough attention.
Comment 16 Ivan Bulatovic 2010-02-03 08:33:38 UTC
Easy friend, I'm sure Jesse and the crew are already working on it.

This is not so easy to catch, it appeared againg in both 2.6.32.7 and 2.6.33-rc5, and I can do nothing to reproduce the bug on my own will. It just occur randomly, sometimes more often (2-5 times a day), sometimes 2 days without a freeze. I've suspended, turned off lvds backlight, restarted, did all that numerous times and neither once I was able to reproduce it. Just when I give up it shows up by itself. And what is more strange I don't seem to find soft lockup BUG in kernel messages anymore when the freezing occur.

This one seams a bit hard to investigate but if there is anything I would be 100% certain about I will report here. This happenes on a Dell Vostro 1310 laptop with GM965 chipset.
Comment 17 Jithin Emmanuel 2010-02-03 15:52:09 UTC
Downgraded to 2.6.31.5 kernel. Everything seems to be working fine now.
Comment 18 Jesse Barnes 2010-02-05 21:33:40 UTC
Can you try the drm-intel-next branch from the drm-intel repo (git://git.kernel.org/pub/scm/linux/kernel/git/anholt/drm-intel.git)?  It's quite a bit different from 2.6.32, and if the problem is fixed there we'll know we have something to backport.

Another option would be to bisect between 2.6.31 and 2.6.32 when the breakage started and figure out which commit broke things for you.
Comment 19 Ivan Bulatovic 2010-02-05 23:35:02 UTC
Bisecting would take a lot of time because this bug occurs randomly, for 3 days I havent had a lockup and today happened again with the same error when I've tried to reboot:

Feb  5 14:59:01 vostro kernel: [24919.401005] BUG: soft lockup - CPU#0 stuck for 61s! [Xorg:2086]

I'm cloning the drm-intel-next and report here if the bug occurs again. I havent had any printk's because I didn't wait long enough for it to occur so last time I waited a minute or two before I've powered down my laptop and found it this time in /var/log/everything.log

I also got this in .xsession-error

It looks like X tried to respawn itself upon reboot and triggered the bug, CPU must be on 100% load because my fan spins like crazy but all I see is a black screen with cursor in the top left corner.

I really don't know if this two errors are related but I've rebooted to init3 upon restart because I didn't want to taint log files with new output.

This is definitly not related to compositing or DE because it happened on KDE with kwin and compositing disabled also.

I hope I'll have some good news in a few days with the drm-intel-next.
Comment 20 Ivan Bulatovic 2010-02-08 14:07:27 UTC
Bug is still present.

Linux vostro 2.6.33-rc5-TESTING-50523-g0d0e2fe #1 SMP PREEMPT Sat Feb 6 01:45:04 CET 2010 x86_64 Intel(R) Core(TM)2 Duo CPU T5670 @ 1.80GHz GenuineIntel GNU/Linux

It froze upon restart again, I've turned on almost every debugging option in kernel hacking section and still there was no output whatsoever. I've waited for 5min before powering off hoping it will provide some information. 

Good news is that it didn't froze while turning off lvds or waking up from suspend for three days period since I've tested it.
Comment 21 Jesse Barnes 2010-02-08 21:47:14 UTC
There's a patch at the end of https://bugs.freedesktop.org/show_bug.cgi?id=24314, I'm curious if it helps with this issue.

If not, it makes sense to add a timeout to our disable routine.  I'll attach a patch for that.
Comment 22 Jesse Barnes 2010-02-08 21:52:02 UTC
Created attachment 24958 [details]
return early and timeout in FBC disable path

Check FBC status when disabling, and add a timeout to the disable if we end up spinning.
Comment 23 Ivan Bulatovic 2010-02-09 23:40:15 UTC
I've applied both of these patches to the drm-intel-next, even though I can't trigger the bug described in the freedesktop bugtracker. Works fine for me in those situations, playing video after suspend doesn't hang the gpu and there are no desktop glitches. Although I have a different test system.

00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

I only have Projection and LOD, Bypass FIFO and Color calculator on 100% but I think that's normal.

I'll be on a lookout for that bug upon restart. Can I apply these patches to the 2.6.33-rc7 as well and will they be included in the 2.6.33-rc8?

Thanks Jesse.
Comment 24 Jesse Barnes 2010-02-09 23:46:03 UTC
I'm hoping they'll be in -rc8; depends on whether Eric gets back in time to do a batch of patches before Linus decides to drop -rc8 on us.
Comment 25 Jesse Barnes 2010-02-09 23:49:43 UTC
Oh and would it be possible for you to isolate which fix prevents the blank screen for you?  I'm hoping the one from comment #21 is sufficient, since the one in #22 is more a workaround...
Comment 26 Ivan Bulatovic 2010-02-10 00:16:53 UTC
That wouldn't be a problem, I'll patch 2.6.33-rc7 with the one from #21 and leave intel-drm-next with both of them. I can't be certain when I'm gonna have some results because in the last six days it only happened twice. I'll try my best to figure out how to trigger this bug for sure.
Comment 27 Ivan Bulatovic 2010-02-13 19:45:31 UTC
Ok, with the 2.6.33-rc7 and the patch from comment #21 only I couldn't reproduce the bug for 3 days now, done everything to trigger it but no show. So it looks good. I've compiled 2.6.33-rc8 today (clean) and I'll see if it locks again. I saw the FBC_C3_IDLE patch entered the rc8 but only for 945GM so if it locks with rc8 then I think that FBC_C3_IDLE should be included for 965GM also.

*** Bug 13453 has been marked as a duplicate of this bug. ***
Comment 29 Jesse Barnes 2010-02-18 23:11:17 UTC
Sent out the 965 version as well.
Comment 30 Ivan Bulatovic 2010-02-18 23:56:04 UTC
Ok, 2.6.33-rc8 clean with no patches, works like a charm. No problems at all. 5 days of testing with big uptime, suspending, restarting, playing games, video etc. So it works for me.

off: I got 3D performance increase of 30% with rc8 compared to rc7. 22 to 33fps jump on urban terror. No mesa/xf86-video-intel upgrades in the meantime. Great work...
Comment 31 James 2010-05-21 07:29:16 UTC
Jesse's patch in Comment #22 works for me, too (solved the DPMS latency problem) --- in which mainline release is it included?
Comment 32 Jesse Barnes 2010-05-21 16:23:47 UTC
James, which chipset do you have?
Comment 33 James 2010-05-21 16:29:07 UTC

Intel X3100.
Comment 34 Jesse Barnes 2010-05-21 16:39:14 UTC
Arg I thought 965 had working FBC, but maybe it's broken on your platform somehow.  We disabled it on 945, which fixed this bug for most people, but it looks like the timeout is still needed for some.  I'll push it now.
Comment 35 Ivan Bulatovic 2010-05-21 16:42:39 UTC
Well I haven't had these problems since 2.6.33-rc8, 965 also...

Noted. For co-ordination purposes: I've been applying it to all the kernels I've built, up to the most recent (which is based on 2.6.33); things seem to work just great with it.

Jesse, in which kernel version was fbc-disable-timeout merged (for 965)? It doesn't seem to be in any of my distro's recent kernels, I still need to rebuild them with this patch...
Comment 38 Jesse Barnes 2010-07-09 16:26:48 UTC
It's in git, so it should be in 2.6.35.  If you want it in a stable kernel release for your distro to pick up you can send the commit id to stable@kernel.org and request that it be merged.
Comment 39 James 2010-07-25 10:22:31 UTC
Sorry to keep bringing this up again. I've been doing some testing of vanilla kernels 2.6.34.1 with and without the fbc-disable-timeout patches applied (had suspicious about the F13 sources).

What I have found is that with or without the patch applied, the DPMS-off/screensaver fade latency issues remain (e.g., repeating/skipping audio), IF the kernel is compiled with voluntary pre-emption. On the other hand, if I compile it with full pre-emption, the spike in system CPU activity is still visible but the latency issues do not manifest so badly. [Since Fedora seem to have no intention of building kernels with full pre-emption, I doubt their 2.6.35 series will have this fixed.]

So it appears as if there is something left here from Bug 13453; would it do to re-open this old bug?
