           Summary: [r300g] general/draw-vertices-half-float causes GPU
                    reset
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: plaes@plaes.org


Chipset: "ATI Radeon Mobility X300 (M22) 5460 (PCIE)" (ChipID = 0x5460)
Kernel 2.6.35
Mesa: GIT master: d64a119c28376d7ce069dcec044ff9af7f93ff9c
xf86-video-ati: git-master

After experiencing some hangups while checking out Enemy Territory, I decided
to see whether running piglit can shed some light:

Test error:
[snip] 
Returncode: 234
Errors: drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command
stream. See dmesg for more info.

Output:

PS. Should I file separate bugs for other less serious piglit  test errors?
