I thing the Linux driver is confused here - the device is
an on-board controller with a single cable plugged in (and a single disc
on the other end of it). Termination disabled in Adaptec BIOS (and driver
complains even when I enable the termination in the BIOS).

But the problem is most probably not in the kernel space -
I have compiled a non-SMP 2.0.36, booted it, and ran
"make -j 10 'MAKE=make -j 10' bzImage", and the compile crashed with
"undefined symbol `kern1l_something'" (note the "1" instead of "e").
So I think the problem is in a buggy HW. Q.E.D.
