I'm running on a 2.6.11 kernel, it should be pretty up to date.

I forgot to mention that it only occurs if the drive is removed from the
RAID5 set before it is 'synced' for the first time.

Could it be the mddev->curr_resync or mddev->recovery_cp are handled wrong
in this case? I saw the prints:

..
Jun 23 12:26:10 172 kernel: md: checkpointing recovery of md3.
..
Jun 23 12:26:15 172 kernel: md: resuming recovery of md3 from checkpoint.
..

in the error situation, while there is no state to recover at all at that
point (the array is incomplete/degraded).

Cheers,
	Bart
