Comment 34 for bug 564181

I'm still experiencing similar effects. Firefox triggers the "[drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation !" messages when scrolling up/down fast. Sometimes Xorg freezes. Remote ssh is still possible, but I didn't get a shell, just motd. At one occasion it didn't crash complete and i got the following dmesg output (attachment). Xorg.0.log is not reporting anything special. Maybe it's a different bug, but the message is still the same...
