Hi there ... After having installed a HP C1599A 4 Gig DDS2 tape drive my system has been reebooting everytime I use the DAT drive. I have the following components installed FreeBSD 2.1.7.1 Adaptek 2940 2 X @ Gig IBM DORS SCSI disks (running as one ccd device) 1 X HP C1599A DAT drive (hardware compression enabled SCSI ID 6, termination off) Sequence Adaptek----->st0------>sd0-------->sd1(term) Before I installed the HP C1599A I used to do backups using an external HP 2 Gig drive without any problems !! So I'm not sure if the problem lies with the device driver for the 2940 ISA Adaptek (a bit old :) ) The following happens. The backing of a backup seems fine: tar -cvf /dev/rst0 / but when doing a tar -dvf /dev/rst0 It seems to run up to a point and then the following is displayed in the logs an on the console May 29 14:09:02 oskar /kernel: st0(ahc0:6:0): timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 May 29 14:09:02 oskar /kernel: SEQADDR == 0x11 panic ahc0: Timed-out command times out again syncing disks ... 135 135 135 ..... giving up followed by a reboot. This morning I tried to do a "mt -f /dev/rst0 erase" And got the following in the logs and on the console May 30 10:36:53 oskar /kernel: st0(ahc0:6:0): timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 May 30 10:37:04 oskar /kernel: SEQADDR == 0x11 May 30 10:37:04 oskar /kernel: Abort Message Sent May 30 10:37:04 oskar /kernel: sd1(ahc0:1:0): timed out in message out phase, SC SISIGI == 0x0 May 30 10:37:04 oskar /kernel: SEQADDR == 0x0 May 30 10:37:04 oskar /kernel: st0(ahc0:6:0): abort message in message buffer May 30 10:37:04 oskar /kernel: st0(ahc0:6:0): timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 May 30 10:37:04 oskar /kernel: SEQADDR == 0x10 May 30 10:37:04 oskar /kernel: ahc0: Issued Channel A Bus Reset. 1 SCBs aborted May 30 10:37:04 oskar /kernel: Clearing bus reset May 30 10:37:04 oskar /kernel: sd1(ahc0:1:0): UNIT ATTENTION asc:29,0 May 30 10:37:04 oskar /kernel: sd1(ahc0:1:0): Power on, reset, or bus device re set occurred May 30 10:37:04 oskar /kernel: , retries:4 May 30 10:37:04 oskar /kernel: Clearing 'in-reset' flag May 30 10:37:34 oskar /kernel: sd0(ahc0:0:0): UNIT ATTENTION asc:29,0 May 30 10:37:34 oskar /kernel: sd0(ahc0:0:0): Power on, reset, or bus device re set occurred May 30 10:37:34 oskar /kernel: , retries:4 May 30 10:42:04 oskar /kernel: st0(ahc0:6:0): timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 May 30 10:42:04 oskar /kernel: SEQADDR == 0x11 followed by a reboot .... after about 5 minutes Here is an extract from dmesg ... ahc0 <Adaptec 2940 SCSI host adapter> rev 0 int a irq 10 on pci0:19 ahc0: aic7870 Single Channel, SCSI Id=7, 16 SCBs ahc0 waiting for scsi devices to settle (ahc0:0:0): "IBM DORS-32160 S82C" type 0 fixed SCSI 2 sd0(ahc0:0:0): Direct-Access 2063MB (4226725 512 byte sectors) (ahc0:1:0): "IBM DORS-32160W WA6A" type 0 fixed SCSI 2 sd1(ahc0:1:0): Direct-Access 2063MB (4226725 512 byte sectors) (ahc0:6:0): "HP C1533A A612" type 1 removable SCSI 2 st0(ahc0:6:0): Sequential-Access density code 0x24, drive empty Probing for devices on the ISA bus: Thanx Reinier
