Neil,

Was anything ever done with this idea?  I can throw my hat into the 
this-is-a-big-problem ring.  I oftentimes have a RAID1 disk fail on a 
heavy-I/O system and the system basically needs to be power-cycled if it 
is to come back up within the hour (any OS access to that RAID will hang).

Any word would be appreciated.
