Hi, My newsfeeding-box (running FreeBSD-2.2.6) keeps crashing once or twice a month with these messages : Aug 5 15:43:33 feedme /kernel: sd1(ahc1:2:0): SCB 0x1 - timed out in dataout phase, SCSISIGI == 0x4 Aug 5 15:43:33 feedme /kernel: sd1(ahc1:2:0): SCB 0x1 - timed out in dataout phase, SCSISIGI == 0x4 Aug 5 15:43:33 feedme /kernel: SEQADDR = 0x121 SCSISEQ = 0x12 SSTAT0 = 0x0 SSTAT1 = 0x2 Aug 5 15:43:33 feedme /kernel: SEQADDR = 0x121 SCSISEQ = 0x12 SSTAT0 = 0x0 SSTAT1 = 0x2 Aug 5 15:43:33 feedme /kernel: sd1(ahc1:2:0): abort message in message buffer Aug 5 15:43:33 feedme /kernel: sd1(ahc1:2:0): abort message in message buffer Aug 5 15:43:34 feedme /kernel: sd1(ahc1:2:0): SCB 0x0 timedout while recovery in progress Aug 5 15:43:34 feedme /kernel: sd1(ahc1:2:0): SCB 0x0 timedout while recovery in progress Aug 5 15:43:35 feedme /kernel: Unexpected busfree.

I've tried replacing the scsi-cables and terminators without any effect.
