Bug#498518: found more in logs
I also found this in kern.log. The system is unstable, few reboots were
needed in the last three hours and debian package management utilities and
even other binaries keep segfaulting from time to time (I don't know if
it's the kernel to blame for this or just the /var/lib/dpkg/status or
/var/lib/dpkg/available files which were corrupted after the kernel bug was
hit).
