Then, on the console (and in the log files) there are long rows of: goelz /kernel: (da0:ahc0:0:0:0): SCB 0x85 - timed out in datain phase, SEQADDR == 0x5e goelz /kernel: (da0:ahc0:0:0:0): BDR message in message buffer goelz /kernel: (da0:ahc0:0:0:0): SCB 0x85 - timed out in datain phase, SEQADDR == 0x5e goelz /kernel: (da0:ahc0:0:0:0): no longer in timeout, status = 34b goelz /kernel: ahc0: Issued Channel A Bus Reset. 78 SCBs aborted repeating all the time - until manual reset of the machine (often, even telnet doesn´t work any more). Usually the problems start with da0 and then switch to the other drives.
