Nouveau - Jun 2011 - [Bug 37894] New: After sleep/hibernate, X crashes after a few minutes

https://bugs.freedesktop.org/show_bug.cgi?id=37894

           Summary: After sleep/hibernate, X crashes after a few minutes
           Product: xorg
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: pablo at blueoakdb.com
         QAContact: xorg-team at lists.x.org


Created an attachment (id=47492)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=47492)
tar-ball with the initial files 

[ I originally filed this bug against "openSUSE" [1] and tried the
recommended
fix:  install latest Nouveau GIT builds [2] ]

Howdy,

I have an issue where resuming from a "suspend", X will crash.  I have
had this
issue with both the Nvidia and nouveau driver.  Given the nouveau driver is
OSS, I figure it's easier to debug so it's currently installed on my
laptop
[3].

Per Johannes Obermayr, I'm uploading a tar-ball with the following:

o dmesg
o /var/log/messages
o Xorg.0.log
o Xorg.0.log.old

Please note the crash occurred at 15:29:10 - see the following message in
`messages':

    Jun  3 15:29:10 zoom kdm[1581]: X server for display :0 terminated
unexpectedly

When I say X crashes, what happens after a resumption is I end up in the login
screen.

I'm marking this ticket as "critical" because when X crashes, any
unsaved work
is lost.  :(

Please let me know if you need any additional forensics.

Hi pablo

When Johannes Obermayr mentioned to try the latest git, he could/should have
mentioned that nouveau consists of four components - kernel module, libdrm, ddx
and mesa (3d)

That aside I have a few simple things you can try to narrow the issue

1. Confirm it's not a KDE issue (try with gnome, lxde, ...)
2. Use a minimal xorg.conf [1]
3. Try disabling AIGLX in xorg.conf
4. If the above fails append "nouveau.noaccel=1" to your kernel
command line

Although if you are interested in trying the latest git please follow these
instructions [2]

Hi Emil,

I apologize for not being clear.  Johannes did mention that I install the four
components.  I ended up installing the following (and including some of the
-devel packages simply because I have the Dev environment on this laptop):

o Mesa
o Mesa-devel
o Mesa-nouveau3d
o drm-nouveau-kmp-desktop
o libdrm
o libva1
o libllvm
o xorg-x11-driver-video
o xorg-x11-driver-video-nouveau
o xorg-x11-proto-devel

I don't see `ddx' but a little googling seems to imply that'd be the
`xorg-x11-driver*' packages.  I hope so.  :D

Thank you for the hints on narrowing the issue.  I'll try them and report
back.
 Unfortunately it's a bit like painting the cuckoo in a cuckoo clock,
without
the benefit of advancing time, it takes a few hours for the problem to manifest
itself.

Thanks again!
-pablo

Hi Emil,

A quick update ...

First I tried "KDE" + "minimal xorg.conf", which didn't
work.

Next, I tried "gnome" + "minimal xorg.conf" and after nearly
48 hours, no
issues.

The above suggests some type of KDE issue.  This is good news.  Now, I need to
ponder the next step.  I think I may open a KDE bug with "openSUSE" to
get some
direction from those folks because I'm not exactly sure how to proceed.

Of course, any ideas would be most welcomed!

Also, should I close this bug?

Thx a lot!
-pablo

Hi pablo

I believe that we can close this bug as "notourbug" and I would
appreciate if
you can link the bug you opened with the KDE team.

In such a way any other users can take a look and/or monitor the progress.

Although if you have problems with other DE (gnome, lxde..), or it turns out
that "nouveau is doing something wrong" please reopen the bug with a
bit more
information.

Thanks

Hi Emil,

Once again, thank you /very/ much for your consideration.  I'm adding the
openSUSE bug URL as requested.

Through bifurcation, I /believe/ I've narrowed the issue with the
`x11vnc'
package.  As each test-run can take up to 24 hours, I can't say with
certitude
that it's `x11vnc'

Cheers,
-pablo
