Kernel: 2.6.38-RC2 MESA: 7.10 with gallium and llvm enabled. Driver: xf86-video-ati git master Kwin: 4.6 RC2 When desktop effects is enabled. Launch glxgears and play around desktop effects, e.g. Present Window effect. System will lock up. Can not telnet to the machines anymore. Drm debug log only collected a bunch of garbage characters at the time when system locked up.
(In reply to comment #1) > MESA: 7.10 with gallium and llvm enabled. Does it also happen with the classic driver? What card is it? (Maybe attach Xorg.0.log and dmesg) > Drm debug log only collected a bunch of garbage characters at the time when > system locked up. Maybe you can get more information with netconsole.
Created attachment 42801 [details] dmesg
Created attachment 42802 [details] xorg.log
Created attachment 42803 [details] xorg.log.gallium
I am using a R300 PCI-E. Seems classic driver does not have such issue.

Could you try latest kernel 2.6.38-rc*, latest xf86-video-ati from git, and r300g from the Mesa master branch?

Does disabling page flipping help?
Kernel: 2.6.36 and 2.6.38-RC4 MESA: 7.10 with gallium and llvm enabled. Driver: xf86-video-ati 6.14.0 WM: Kwin 4.6.0 and TWM Card: Radeon Mobility X300 I have the same problem with the hardware listed above (Bug 34302). Disabling page-flipping does not help.
Does this kernel patch help? https://bugs.freedesktop.org/attachment.cgi?id=44345
Seems the patch works!
Closing because the patch is now part of kernel 2.6.38.
