Nouveau - Jan 2013 - [Bug 59057] New: Black screen after resume from s2ram

https://bugs.freedesktop.org/show_bug.cgi?id=59057

          Priority: medium
            Bug ID: 59057
          Assignee: nouveau at lists.freedesktop.org
           Summary: Black screen after resume from s2ram
        QA Contact: xorg-team at lists.x.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: pontus.fuchs at gmail.com
          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:

nouveau E[     PFB][0000:01:00.0] trapped read at 0x002001a020 on 
channel 0x00007b23 SEMAPHORE_BG/PFIFO_READ/00 reason: PAGE_NOT_PRESENT

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.

Quoting http://nouveau.freedesktop.org/wiki/Bugs:
"Please, do not compress files you attach to bug reports, especially plain
text
files such as logs, unless the file is so huge bugzilla refuses to take it.
Gzipping files makes taking a quick look impossible".

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.

I have tested it today with kernel 3.8.1 and suspend seems to work correctly...
at least with an external display attached both lcd and it wake up.

if someone can confirm it too.. maybe we shall close it as solved?
