This is on 5.0.2 generic, but I've also tried 4.0.1 generic.  console  
errors
are the fairly generic device timeout messages when I/O is heavy  
(such as
forcing fsck on 14 spindles at once), and not recoverable (reboot  
necessary).

I will probably end up just switching to a siop or aha driven  
controller.  I
know that mpt is still considered experimental and buggy, so no  
problem with that.
