Thanks. I agree that we do need something along these lines. It
might be a while before I can give the patch the brainspace it
deserves as I am travelling this fortnight.

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.
