Bug#631976: kernel BUG when mounting btrfs volume
Package: linux-image-2.6.32-5-486
I'm seeing a kernel bug when trying to mount a btrfs volume.
I see the same bug when i boot with 2.6.39-2-686-pae, fwiw, though i
have only been able to transcribe it thus far with 2.6.32-5-486. This
is on standard x86 hardware (a Dell Dimension 4500S desktop machine):
