Description

Steps to reproduce:

First mount the root somewhere

mount -t ceph a.b.c.153:6789:/ -oname=admin,secret=... /mnt

Unmount root:

umount /mnt

Try to mount a nonexistent path:

mount -t ceph a.b.c.153:6789:/idonotexist -oname=admin,secret=... /mnt

At this point the kernel panics. The entire panic is attached.

Kernel is a stock 3.5.1 kernel. The .config file is attached.
Problem also appears on a 3.4.7 kernel
The server is running under kvm 1.0

ceph version is 0.48argonaut-1~bpo60+1
