I already said that:
1. This controller and disks succesfully works earlier with FreeBSD 4.6.2
without any problems;
2. I tried to replace a disk with another one (the same model), but it
doesn't help. Unfortunately, I have no another free SCSI controller (but see
3. I have another AMD64 machine with different hardware (including disks and
SCSI controller) that periodically suffers from the same problem.
Unfortunately, that machine is in production and heavily loaded, so I can't
overload it even more with INVARIANTS, WITNESS, and DIAGNOSTIC - my clients
will not forgive me for that.
