           Summary: xf86-video-ati 6.14.0 hard freeze in fullscreen OpenGL
                    applications
           Product: DRI
           Version: XOrg CVS
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: gabgav@hotmail.com


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

System locks up after running a fullscreen OpenGL application (e.g. glxgears
and hedgewars). Using 2.6.38-RC4, the system locks up almost immediately after
starting the application. With 2.6.36, glxgears does not lock up the system,
but hedgewars does after a short period of time. 
KWin runs well and does not cause a system lock in either case. Running the
programs under TWM also causes a lock up.
xf86-video-ati 6.13 ran well.
The lock up occurs with and without polling (Bug 29389).
Occurs only with Gallium3D, classic runs well
dmesg output at time of lock up was:
[ 1290.006008] Uhhuh. NMI received for unknown reason a1 on CPU 0.
[ 1290.006008] You have some hardware problem, likely on the PCI bus.
[ 1290.006008] Dazed and confused, but trying to continue

Does disabling pageflipping (in the device section of your xorg.conf) help?

Option "EnablePageFlip" "False"
