Similar issue here on Compaq nc6230, Radeon Mobility X300 (radeon driver). Xserver freezes up, cursor usually moves jerky, CPU goes up to 100%, sometimes the CPU stays low and cursor moves normal. The no keyboard / mouse response followed by the backtrace in Xorg is always consistent. If I ssh in remotely I always see "[mi] EQ overflowing. The server is probably stuck in an infinite loop." followed by the backtrace. Gnome, Compiz w/ Emerald, console frame buffer disabled due to performance issue with Compiz (nomodeset kernel option). Occurred once or twice a day, randomly.
I was forced to downgrade the Xserver / kernel to the 9.10 version, my system has been stable since then. I need to keep a close eye this bug, I will not upgrade to 10.10 until this Xserver issue is resolved. Thank you. ** Attachment added: "3 separate xorg crashes" http://launchpadlibrarian.net/53053734/Xorg.0.log-crashes.tgz -- [Radeon] [Lucid] [mi] EQ overflowing.
