Package: src:linux
Version: 3.2.23-1
Severity: grave
On a very fresh wheezy install I was able to crash the kernel by
playing with btrfs. I am reporting it using a kvm image but I first
had the bug on real boxes.
To reproduce the bug, I am creating a "raid1" btrfs filesystem,
creating some file and stopping the system:
# mkfs.btrfs -m raid1 /dev/vdb /dev/vdc
# mount /dev/vdb /mnt
# dd if=/dev/zero of=/mnt/zeros count=1M
# umount /mnt
# shutdown -h now
While it is stopped, I wipe one of the drive to make it invalid
(/dev/vdc). I can now restart the system, mount the btrfs filesystem
in "degraded" mode and when I want to add a new device to replace the
faulty one, it crashes:
# mount -o degraded /dev/vdb /mnt
# btrfs device add /dev/vdc /mnt
Here is the output of the kernel crash:

It should be straightforward to reproduce. I would flag it as "grave"
as it means one cannot recover a situation when 1 drive is lost in a
RAID1 arrangement.
