I'm just reproducing the lock up I detailed last time, and I remembered that
I also saw these messages on the console before the deadlock:

end_request: I/O error, dev 07:00 (loop), sector 3274
end_request: I/O error, dev 07:00 (loop), sector 3276
end_request: I/O error, dev 07:00 (loop), sector 3278

Not entirely sure what's going on here.. I'll merge in the test1 -> ac19
changes later and see what happens.
