Looks like a slightly broken error handling case.  The file system was
marked as having errors before because of a failure caused by cabling
issues (grumble), and I had skipped the fsck accidentally. Anyway, it
might be worth investigating.  No other errors occurred before this
since boot.

EXT3-fs error (device md0): ext3_free_blocks: bit already cleared for block 403020800
Aborting journal on device md0.
