I'm starting to think this is a bug in the raid4-5 driver. I'm seeing
this in my kernel log:
Dec 22 21:56:30 faldara kernel: [ 1939.397600] device-mapper: ioctl: device
doesn't appear to be in the dev hash table.

And then the dmraid process becomes stuck in the uninterruptable state.
Can you check your kernel log for similar entries, and if dmraid -ay
becomes stuck, hit alt-sysrq-w and it should add lines to the log that
look something like:
