            Bug ID: 86115
           Summary: Suspend to RAM fails when using Nouveau
           Product: xorg
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: lars-eUNUBHrolfbYtjvyW6yDsg@public.gmane.org
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org

The system in question has a NVIDIA Corporation G84 [GeForce 8600 GT] (rev a1)
graphics card installed.

Triggering suspend to memory works but the resume fails and leads to blinking
shift and scroll lock keyboard leds.

This is a fresh install, no upgrade.

With the same hardware suspend to memory worked with openSUSE 13.1.

I've also tested kernel-vanilla 3.18.rc3.next.20141106-1.1.g2af2e06 and it
shows the same defect as with openSUSE 13.2.

Via netconsole I had been able to capture an even more detailed trace with
no_console_suspend set.  Thanks to Takashi Iwai for his debugging hints.

The same initially was reported at the SUSE bug tracked as it was first seen
with the openSUSE 13.2 kernel-default.

--- Comment #6 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
There was a change which fixed fbcon acceleration after resume -- before it
effectively switched into software mode on resume, but that got fixed.
Unfortunately if the GPU is unhappy on resume, that means that the console also
hangs.

Specifically it was commit ecf24de071f4f6cea79ecef5d990794df5875ee1. Could you
test a few kernels to see whether it's the same issue you're seeing?

e.g. does 3.14 work while 3.15 fails? If so, can you do a bisect to confirm
(and if not, also do a bisect to figure out what broke it).

git bisect start v3.16 v3.13 -- drivers/gpu/drm/nouveau

should cover the whole range you mentioned (3.13 = good, 3.16 = bad).

Separately, could you attach a full dmesg after boot? That should answer a
number of basic questions about some of your setup's specifics. Additionally,
how is your monitor(s) connected?

FYI, there are a few kernel packages available in OBS home:tiwai:kernel:3.13,
home:tiwai:kernel:3.14, and home:tiwai:kernel:3.15 repos.

For 3.12, you can use OBS Kernel:SLE12.  Kernel:stable is for 3.17, and
Kernel:HEAD is for 3.18-rc.

Doh, sorry, I wanted to see the result with *disabled* async  PM.

Lars, please retest with

   echo 0 > /sys/power/pm_async

Certainly there is a GPU hang at PM, but I'd like to know whether it's the real
culprit of the whole hang.

Retest S3 after calling: echo 0 > /sys/power/pm_async

With /sys/power/pm_async set to 0 the system no longer crashes while resume.

I'm able to ssh into the system but x.org doesn't come back.  The two screens
stay black.

OK, then I guess you're seeing two distinct issues.  One is the broken graphics
by S3, and another is the kernel panic due to the stall of disk PM.  Disabling
async PM seems curing the latter while the graphics remains broken.

Could you try to boot with nomodeset boot option in runlevel 3, and try S3, but
without pm_async adjustment?  The graphics can be broken in this case after S3,
but if the system alives, you should be able to remote-login.

If S3 crashes even without nouveau, we can check the two issues above
completely separately.  If S3 crash happens only with nouveau, it implies that
the disk problem is somehow related with nouveau problem.

It crashes even without nouveau when booted with nomodeset set.

You could try to boot and test with

modprobe.blacklist=nouveau to make sure the module isn't loaded.

If you really have time on your hands, try to bisect the problem: 3.11 as a
good starting point and 3.13 or 3.14 as bad, but that will really eat time :)
