Comment 18 for bug 416001

I have a Compaq Evo N600c with ATI Radeon Mobility M6 LY 32MB running with xubuntu 9.10 and can confirm that AccelMethod EXA fixes the drawing problems with the notifications.
The big problem is that my system is still not stable with radeon module, i.e. after some time of 2-D usage (30min-2h) the system locks up (mostly soft-lockup). I used openSuse 11.1/2 before and could still get kernel debug messages/sysrq key responses via network debug. (in opensuse 11.0 I used fglrx, which was stable). So I use vesa most of the time, which is quite slow. To watch a movie or sth., I save my work and switch to the radeon module.
To test if, an especially how stable the system is (for ex. with different xorg.conf options), I start etracer (extrem tux racer). It reliably locks up the system (didnt with fglrx some years ago). With no option quite fast in the startup menu, with EXA the menus seem more or less stable, though have drawing errors.
I would be glad if someone can help me and tell me what and how to debug / whether to file a new bug report.
