I have set up a test server, P2B/DS PII 400Mhz and couple SCSI drives, and it has been running buildworld for over a day without a panic. With the 3 inn's crashed in this thread, I think we can rule out the type of ahc (W, U2 and U160), CPU (PII/III/speed) or SMP. However, all 3 have an ata/ahc combination and more than one ahc. I will try to dig up another ahc and see if I can duplicate the problem with the test server. Of course, the other thing missing is network traffic.
