I would suggest the following: 1) Check that your SC-200 is configured for PCI INT A. If it is not, change jumpers accordingly. 2) Move you board to another PCI slot. 3) Check/set SCSI termination properly. If either (1) and/or (2) and/or (3) does not cure, then send me any dmesg you have. You also could try to catch manually driver messages that look like complaint about something going wrong under FreeBSD and/or Linux as well. The fact that your system experiences the problem also under Linux and given that the ncr(4) driver (used in 3.4) also polls interrupts using a timer, it might well be that hardware interrupts are not functionning properly for your SC-200 (just a guessing).
