Using latest git (as of 12/08/2010) of libdrm, mesa(classic),xf86-video-ati and drm-radeon-testing (commit drm/radeon/kms: enable writeback on remaing asics ), gpu is a hd3470 mobility (rv620), forced to lowest power state (echo "low" > /sys/class/drm/card0/device/power_profile). During normal web browsing, maybe while playing a flash video, the mouse cursor suddenly stops and immediately after I get a black screen from which I cannot recover unless I sysrq-reboot (haven't tried ssh). Upon reboot a check of the system log shows
