I have a similar situation, a machine with an aha1542cp and IBM/Connor
DAT has much the same troubles when running 2.0.x or 2.2.x kernels.
However the identical hardware runs sweet under 1.2.13! It's a
situation where I was preserving a dual-boot environment while
attempting an upgrade.
I asked this list for help in May, and the most constructive
suggestion I got (from Matthias Andree) was to "get a decent SCSI host
adapter". Let us hope for no end of interesting weather where he lives.
I did find one improvement on my own, an improper processor flag
setting under the newer kernels. However the lower SCSI reliability,
and descent into error-recovery hell, remains. So I preserve the old
boot partition for now. The newer kernels are simply not as robust.
