kernel BUG at /tmp/buildd/linux-2.6-3.0.0/debian/build/source_amd64_none/fs/btrfs/inode.c:4586!

[Klinkby]

I get an error in dmsg during boot, and have trouble with loading my profile from the home folder.

My fstab says:

# /dev/sda4
UUID=4b52ceed-c9bb-49fb-887e-a624f54fb010 /home btrfs defaults,space_cache,ssd 0 0

And the dmsg dump follows:
