Hi there, seeing this too on Wheezy/SID amd64, sometimes it's just a logout, sometimes it's total X freeze ending up progressively in total machine freeze if let running (no input device working, no ssh access). It happens with stock Debian kernel (Sid) or locally compiled vanilla (3.2.8). Downgrading to 290.10 solves the issue on both Sid and Wheezy. kernel and system logs doesn't show anything meaningful, Xorg.0.log doesn't contain errors that stand out, and xsession-errors is mute too. :-( .
I run KDE desktop with compositing, lockup happens randomly, when session is active or on the screensaver. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
