- From: Moritz Augsburger <debian-bugreport@moritz.augsburger.name>

Package: linux-2.6
Version: 2.6.32-30
Severity: critical
Justification: breaks unrelated software
Starting a vserver with it's root on ext4 crashes ext4, event with
/var/lib/vz on a different partition the root system gets unstable to
unusable. I had hanging dpkgs when trying to extract files and the
system wasn't rebootable because of the hanging guest, only
`echo b > /proc/sysrq-trigger` worked.
