I had a similar problem with the nvidia driver which resulted in easy-to-reproduce X server lockups. The Xorg.0.log show the "EQ overflowing" message followed by message that the xserver was in an infinite loop.
The bug is 642497: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=642497 It was fixed by purging the xserver-xorg-video-nouveau followed by reinstall of the nvidia drivers and xserver. If one tries to install the nvidia driver directly from the NVIDIA blog, there is a warning that the presence of shared libs from nouveau may cause problems. After doing this reinstall I've tested extensively and had no problems. --JS -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
