Ah, yes.  I believe you've run into a firmware crash.

Make sure your cards have the latest firmware running.

I've seen cases where hot swapping drives causes the firmware to reset and 
lock up (based on the LED pattern of the diagnostic lights on my cards.)

I added command timeout detection to the driver as a means of detecting 
this condition.  I don't have any good leads on recovinging from it though 
as my test hardware failed and I haven't replaced it yet.
