I have an IWill KA-266R motherboard.
When I start X with DRI, all is good until I
execute anything utilizing OpenGL (I tried tuxracer
and glxgears). When I run an OpenGL app, the system
usually hangs. On a rare occasion I can ssh in to
relevant info from kernel logs:
agpgart: AGP aperture is 64M @ 0xf0000000
[drm] AGP 0.99 on Unknown @ 0xf0000000 64MB
[drm] Initialized radeon 1.1.1 20010405 on minor 0
Kernel version: 2.4.7
X version: 4.1.0
Don't hesitate to email me with questions.
