Yeah, I think I won't be using the 3.0 kernel after tonight. At least the 
older kernel's would just lock up the card and not cause md to boot the disks 
one at a time.

I /really really/ wish the driver for this card was more stable, but you deal 
with what you've got (in my case a $100 2 port SAS/8 port SATA card). I've 
been rather lucky so far it seems, I hope my luck keeps up long enough for 
either the driver to stabilize, me to get a new card, or at the very least, to 
get a third drive for my backup array, so if the main array does go down, I 
have a recent daily sync.
