Bug#549314: xorg: Xorg crashes at random, exactly once
Package: xorg
Version: 1:7.4+4
Severity: critical
Justification: causes serious data loss
My Xorg session crashes without prior notice, roughly during the first 15 Minutes of working. However, I can trigger a crash by typing
dmesg -n 9
as non-root user, wich normally prints 'klogctl: Operation not permitted'. This instantly teminates my session.
Such a crash seems to appear exactly once after a reboot. I.e., after a crash I log in again, and I can run dmesg without problems.
I first noticed these problems after an update, see the excerpt from /var/log/aptitude:

This might be related to Bug #539548. I do not run KDE, using fvwm instead.
I have attached dmesg output, and copies of Xorg.0.log[.old] after a random crash, and after a crash triggered by dmesg. You find them in the respectively named attachments.
