Not normal.  Was it ever synced?
Wait for it to re-sync, then reboot and check the status.
Some people have problems after a reboot.

Cat /proc/mdstat for the ETA and status.

Well, the array re-synced overnight and I re-ran bonnie++ again a couple 
of times this morning with no apparent ill-effect.

To be honest, I'd just had some problems with a loose power cable so I 
suspect that the array was already re-syncing before I ran bonnie.

Thanks,
