Hi,
I've had limited success loading the pas16 scsi driver module (kernel 2.0.30).
If loaded while the sound driver is loaded, it complains that the irq can't be
shared, and that I should unload the sound module first. (which is fair
enough).
I can access the tape drive while the driver is loaded, but it's *tragically*
slow due to the CPU polling.
If I load the pas16 module without sound.o loaded, it hooks onto irq10 (like
it should) but any access to the tape drive (8mm exabyte, works fine) hangs
the machine hard.
I have tried selecting a different irq for the scsi controller (15) but this
didn't help at all.
here's what was logged when trying to use irq15 (which isn't in use by any
other device).

Unfortunately, the pas16 module doesn't allow you to pass the irq as a symbol
from the command line, and recompiling the module to test a different setting
is also painful.
Anyone had similar experiences? or any ideas?
