Here is my setup:

1 ST34572N rec 0876 on the internal SCSI bus
1 Plextor ultra SCSI CD-ROM on the internal bus
4 HP C1599A 4mm DAT drives on the external bus
1 ST34752N in a Kingston carrier on the external bus

Linux 2.0.33 w/ latest AIC drivers, and 2.1.87 w/ standard AIC drivers.

When I format and mount the external 4GB drive everything is fine. But when
I read a dd image from the external HD to a single HP drive I get, under
2.0.33:

AIC7xxx unknown REQINIT message type
KERNEL PANIC

Using 2.0.87 I get a HUGE string of parity errors, and other weird messages. 

The cables are high quality Granite Digital teflon, and a GD active
terminator. All external cables are teflon. I can read images off the
internal HD all day long with no problems. These symtoms have happened with
4 different external drives, all with the same errors.

Slowing the bus down, turning off ultra SCSI, etc. still does not resolve
the problem. 

Any suggestions?
