Hello, first off, you should ask in freebsd-questions or freebsd-scsi second this is a typical scsi problem. To solve: - check cables - check termination and if the problem still exists, check again. I speak from my own expierence, since I had this kind of problems one year, cos I didn't see that there were two jumpers on the disc to set the termination :-( Greetings Andreas On Wed, 27 Sep 2000, Zhiui Zhang wrote: > > I am debugging a program that does a lot of disk I/O and the system hangs > briefly with the some repeated messages that looks like: > > (da0:ahc0:0:0:0): SCB 0x0 - Timed out in Data-in phase, SEQADDR==0x88 > (da0:ahc0:0:0:0): BDR message in message buffer > (da0:ahc0:0:0:0): SCB 0x0 - Timed out in Data-in phase, SEQADDR==0x89 > (da0:ahc0:0:0:0): no longer in timeout, status= 34b > ahc0: Issued Channel A Bus Reset. 2SCBs aborted.
