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...
