I have also seen the same error today. I wonder if it is related?
Intrepid 8.10 Full updates as of 19th Oct 2008 (yesterday). xserver-xorg-video-intel 2.4.1-1ubuntu9 Intel Corporation 82G33/G31 Express Integrated Graphics Controller Machine hanging after X/GDM filled / with log files. Machine doing nothing - left during the day running. Got back from work, discovered my desktop PC was "frozen" - at least the graphics were dead (garbage on screen). Constant disk I/O. Logged in remotely via SSH - disk activity was kjournald ..turned out my disk was 100% full. Looking - it was all in /var/log and /var/log/gdm/ - 2x 1 GB log files : /var/log/Xorg.0.log /var/log/gdm/:0.log X/GDM dead. I have saved these files and attach the top 500 lines of each. Stand out : (WW) intel(0): ESR is 0x00000001, instruction error (WW) intel(0): PRB0_CTL (0x0001f001) indicates ring buffer enabled (WW) intel(0): PRB0_HEAD (0x8620bce0) and PRB0_TAIL (0x0000bd20) indicate ring buffer not flushed (WW) intel(0): Existing errors found in hardware state.
