It is currently running FreeBSD 2.2.2. The problem is that is reboots unexpectedly at fairly random times. I managed to find one of the reboots in the log, and it reads: ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@ ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@ ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@ Apr 19 18:59:57 mozart /kernel: SEQADDR = 0x4 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa Apr 19 18:59:57 mozart /kernel: sd12(ahc1:2:0): Queueing an Abort SCB Apr 19 18:59:57 mozart /kernel: sd12(ahc1:2:0): Abort Message Sent Apr 19 18:59:57 mozart /kernel: sd12(ahc1:2:0): SCB 0x5 - timed out in message out phase, SCSISIGI == 0xa4 Apr 19 18:59:57 mozart /kernel: SEQADDR = 0xa1 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT 1 = 0x2 Apr 19 18:59:57 mozart /kernel: ahc1: Issued Channel A Bus Reset. 3 SCBs aborted Apr 19 18:59:57 mozart /kernel: Clearing bus reset Apr 19 18:59:57 mozart /kernel: Clearing 'in-reset' flag Apr 19 18:59:57 mozart /kernel: sd12(ahc1:2:0): no longer in timeout Apr 19 18:59:57 mozart /kernel: sd11(ahc1:1:0): UNIT ATTENTION asc:29,1 Apr 19 18:59:58 mozart /kernel: , retries:4 Apr 19 18:59:58 mozart /kernel: sd12(ahc1:2:0): UNIT ATTENTION asc:29,1 Apr 19 18:59:58 mozart /kernel: , retries:4 Apr 19 19:00:00 mozart /kernel: sd14(ahc1:4:0): UNIT ATTENTION asc:29,2 Apr 19 19:00:00 mozart /kernel: , retries:4 Apr 19 19:00:00 mozart /kernel: sd15(ahc1:5:0): UNIT ATTENTION asc:29,2 Apr 19 19:00:00 mozart /kernel: , retries:4 Apr 19 19:00:00 mozart /kernel: sd13(ahc1:3:0): UNIT ATTENTION asc:29,2 Apr 19 19:00:00 mozart /kernel: , retries:4 followed by ye olde reboote. What exactly is the SCSI chain trying to do? And why should it cause the system to reboot so unhappily? -- Chip Marshall John Leslie Consulting Director of Operations http://www.jlc.net/~chip/ InterNIC handle - CLM21 PGP key available on my web page On IRC via EFnet as Magus To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
