           Summary: RV670 GPU lockup with OpenArena benchmark and kernel
                    2.6.37 rc1/rc2
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: alain.perrot at gmail.com


When running the OpenArena anholt benchmark on my Radeon HD 3870 (RV670, PCIe)
on my 64-bit Kubuntu 10.10 system with kernel 2.6.37 rc1 or rc2, and libdrm,
mesa, xorg-video-ati from git master, I often get a GPU lockup on the level
loading screen.

I can still log into the system through SSH and reboot it, but I cannot kill
the openarena process. There is nothing in dmesg when the lockup occurs.

There is no such issue with kernel 2.6.36 and the same versions of libdrm,
mesa, xorg-video-ati.
