wooowh, i just succeeded in getting a hp-c1533a tape streamer to work on 
my asus P2BD with aha2940 U2W scsi,
it only took about 7 days to find the cause.
there seemed nothing wrong on a nearly identical system
-with no ide, only scsi- i wrote to the streamer flawlessly.

but on the dual pII with ide boot disk,
that had to work in a shared scsi setup,
the tapestreamer would only allow a:
"mt /dev/nst0 status"

[all tests were done in single-scsi-pc with active termination on both
ends ]

any usefull command as: "tar cvzf /dev/nst0 /"
only led to a ghost process that wouldnot stop until a reset.
nothing was written of course.

i tried a lot of kernels including 2.2.14
and another streamer,
and compiling aicxxxx not as a module
and leaving out the ide
and trying to get the aic7xxx on his own irq -thats not simple,
i had to remove all cards from pci-slots-

the simpel solution proves to be:
setting the id of the aha2940 to 7 not 15 as it was.
in none of the nearly 1000 problem-messages i read 
did i find this clue...

maybe this is logical but my 8-bit scsi-cdrom never had a problem with
the controller at id=15

i think scsi-scanners will have the same problems

hopes this helps someone
