BUG: unable to handle kernel NULL pointer dereference at null

[Kees Cook]

Happened in the middle of the night during chroot and VM automatic updates. That would mean a lot of disk IO. It happened 2 minutes after the cron started, so likely not any KVM action yet. It would have all been LVM and ext3 accesses.

ProblemType: KernelOops
Annotation: Your system might become unstable now and might need to be restarted.
