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.

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