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).
