Bug Description

Binary package hint: libgl1-mesa-dri

This happens only under Ubuntu Edgy for me when I run glxinfo.

I'm using a Radeon M6 LY card in a Compaq Presario 1700(US). In syslog, it reports this error:

Aug 25 20:24:29 jakelaptop1 kernel: [17180500.080000] [drm:radeon_cp_reset] *ERROR* radeon_cp_reset called without lock held
Aug 25 20:24:29 jakelaptop1 kernel: [17180500.080000] [drm:radeon_cp_start] *ERROR* radeon_cp_start called without lock held
Aug 25 20:24:29 jakelaptop1 kernel: [17180500.080000] [drm:radeon_cp_idle] *ERROR* radeon_cp_idle called without lock held

These errors are repeated tons and tons of times in the same crash.

Here's my xorg.conf file:
