GPU Lockup log
System: various kernel from 2.6.33 to 2.6.38-pre1
Driver: xf86-video-ati-6.13.2
X-Server: xorg-server-1.9.3
GPU: Radeon 9000 mobility on a GoBook 3
With EXA acceleration enabled (radeon kernel module loaded, irrespectively of
the modeset options) there are multiple issues, like:
- xvideo is slow, often skips a frame and shows the previous one
- GPU lockups on heavy activity (like flash based sited)
- -vo gl_nosw in mplayer works fine but often locks up on exit
I already have agp_mode=-1 in the kernel modeline.
Using "AccelMethod" "XAA" with modeset=0 works fine with everything except
xvideo with 16bpp, it only shows a blue screen (24bpp is OK)
Attached is a typical lockup log (it repeats and I need to reboot with SysRq).
Of course I can give any other log or information needed to solve the issue
