It appears the driver I was using in my pre-release testing is newer 
then the release driver.

Stock driver in 6.2r dmesg:

aac0: <Adaptec SCSI RAID 2130S> mem 
0xfc600000-0xfc7fffff,0xfc5ff000-0xfc5fffff irq 24 at device 1.0 on pci2
aac0: New comm. interface enabled
aac0: Adaptec Raid Controller 2.0.0-1
aacp0: <SCSI Passthrough Bus> on aac0

Currently using:

aacu0: <Adaptec SCSI RAID 2130S> mem 
0xfc600000-0xfc7fffff,0xfc5ff000-0xfc5fffff irq 24 at device 1.0 on pci2
aacu0: New comm. interface enabled
aacu0: Adaptec Raid Controller 2.0.7-1
aacpu0: <SCSI Passthrough Bus> on aacu0

Going to continue testing with the newer driver.

Cheers,

Jeff
