I've had a few problems with the driver in 2.6.20 (fc6xen x86_64). The machine 
tended to lock up after a random period of time (from a few minutes upwards), 
without any messages. Performing a smartctl on all the disks, or leaving smartd 
running, seemed to speed up the rate at which the crash occurred. What I found 
was that by moving the sata_mv device onto it's own bus (or a bus with two 
sata_mv devices), the crashes went away. Are you doing tests with the 
controller sharing a bus with other devices?

Is there an merit to my observation that it might be an issue with devices 
sharing a PCI-X bus?

Cards: Supermicro 5081 (SAT-MV8), Supermicro 6081 (SAT2-MV8), Highpoint 5081 
(RocketRaid 1820A v1.1). Motherboards: Tyan S2882, AMD 8131 chipset; IBM x206, 
Intel 6300ESB.
