sym53c8xx(2) problems on PPC

Greetings.

We recently changed out this card (32-bit card, one channel):

The old card was attached to our SEAGATE   Model: ULTRIUM06242-XXX  Rev: 1470 
for nightly backups.  The backups ran fine.
After attaching the tape drive to the new card, during the backup we get this:

sym0:6: ERROR (40:0) (0-20-0) (1f/18/0) @ (scripta ad8:10001e00).
sym0: script cmd = 10000000

sym0: PCI STATUS = 0x8100

st0: Error with sense data: Current st09:00: sense key Unit Attention
Additional sense indicates Power on,reset,or bus device reset occurred
st0: Error on write filemark.

The system is a powerpc G4 SMP @533mhz, with 1G of ram.  We're using 
kernel-2.4.20, SMP, and HIMEM enabled.  Termination and cabling are definately 
correct.  We tried the sym53c8xx module with both 32 and 40 bit DMA addressing.. 
same results.. the old card works fine, the new card causes these errors and the 
backup aborts.
We'd definately rather use the new 2 channel card, as we'd like to attach a disk 
to the other channel.. but this is preventing us from doing it.  Any ideas? I'm 
up for trying anything here to get this to work.

thanks,
