          Priority: medium
            Bug ID: 59057
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
           Summary: Black screen after resume from s2ram
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: pontus.fuchs-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Driver/nouveau
           Product: xorg

Starting with 3.8rc1 I get a black screen when resuming after suspend. 
The kernel is alive because I can switch to VT1 and reboot with 
ctrl-alt-delete.

I bisected the problem down to this commit:

186ecad21: drm/nv50/disp: move remaining interrupt handling into core

Hardware is 8400M GS (10de:0427) in a Dell XPS M1330.

I see this in my kernel log after resume:

Are symptoms exactly the same with and without the patch from bug 58729?

Please attach full dmesg from 3.8-rcX and 3.7.

I noticed that the machine seems very sluggish after the resume. A little hard
to tell how slow because the screen is black, but I "feel" that rebooting takes
a very long time.

Now, can you verify that with commit 186ecad21 and the fix from bug 58729 you
still see black screen on resume? I'm asking because I think you hit 2 issues
and you bisected the first one. If above combination work, can you bisect
between 186ecad21 and 3.8rc1, applying fix from bug 58729 at each bisection
step?

I tried 186ecad21 + "drm/nv50/disp: fix resume from s2ram for analog output"
but no luck. Still black screen :(

I tried this patch on top of 3.8rc2 and 3.8rc2+"drm/nv50/disp: fix resume from
s2ram for analog output" but no improvement :(

I use only the laptop's panel. I have no external monitor.

some success to be reported...

using nouveau from git master (today's version) I managed to sleep and wake up
and the screen came up correctly...


however as I use kde I had to disable desktop effects as today's master does
not seem to login in kde if they are active...

todays master was compiled against kernel 3.8 desktop flavour.

What version was the latest that failed? Did you spot any particular commit
between the two versions that might be the cause for why it's working again? I
really need to get this fixed. It's very annoying.

Trace dmesg for successful suspend/resume with 3.8.0+ built on 21.2.2013

Latest commit for this build is 2fee6f58d23e7bc2b8d9c599ae1353684043942a.

As in comment #27, suspen/resume works fine.
KDE login ist problematic as it freezes the graphics driver sone of the time.

Suspend/resume and logging in after that worked fine, though, which is what the
attached dmesg shows.
