[dm-devel] Oops in dm-crypt

[Johannes Berg]

Just got the following... Doesn't happen all the time though. My
kernel's at revision 7d59453a9dbe50dc9bab846c410e39f8d5b10c83 which is
from wireless-dev, but there are only the commits
ed45666271f4fafa95b9d8ad44050e9a9bd2376e and
af03b8e4e81c3789e597632268940edd11ffe870 to drivers/md since then.

The partition in question is a LUKS partition and I was using cryptsetup
but I'm not sure I entered the right key, might very well (likely
actually) have been the wrong key.
