Description Ian Pilcher 2011-03-31 04:00:01 UTC 
Description of problem:
With the latest mesa packages in Fedora 15 updates-testing, X appears to hang,
and I get messages about GPU hangs in the syslog:

I tried gathering more information by booting with drm.debug=14, but I
was unable to reproduce the problem.  Race condition?  :-(

Version-Release number of selected component (if applicable):
mesa-dri-llvmcore-7.11-0.1.20110327.0.fc15.x86_64
mesa-dri-drivers-7.11-0.1.20110327.0.fc15.x86_64
mesa-libGLU-devel-7.11-0.1.20110327.0.fc15.x86_64
mesa-dri-filesystem-7.11-0.1.20110327.0.fc15.x86_64
mesa-libGL-devel-7.11-0.1.20110327.0.fc15.x86_64
mesa-libGL-7.11-0.1.20110327.0.fc15.x86_64
mesa-libGLU-7.11-0.1.20110327.0.fc15.x86_64

How reproducible:
X generally gets "stuck" very quickly after I log in to KDE (with KDE
desktop effects enabled).

Additional info:
Downgrading the mesa packages back to 7.10-0.29.fc15 gets rid of the
problem.

dmesg with drm.debug=14

With kernel-2.6.38.2-9.fc15.x86_64, I now get the GPU hangs with
drm.debug=14.  Attaching dmesg.

This shows everything from boot-up until KWin disables desktop effects.
Comment 3 Andy Lawrence 2011-04-05 00:46:53 UTC 
Very similar problem with intel_drv 2.14 (the latest on koji), also compiled and tried with the latest GIT 2.14.902, same problem and output.  Please see the attached logs with drm.debug=0x04 boot parm.

Huh?  Those are already there.

Regardless, 7.11-0.5.20110401.0  seems to have fixed this particular problem.
(I still see occasional GPU hangs, but KWin desktop effects are working for
me again; the situation is basically the same as it was with 7.10-0.29.)

Closing this.

I am sorry, yes, they are.

I am glad it has been fixed, and thank you for letting us know.
