Here's what `dmesg` reports: ahc0 <Adaptec 2940 Ultra SCSI host adapter> rev 0 int a irq 9 on pci0:20 Here are the devices, as well: (ahc0:0:0): "QUANTUM FIREBALL1080S 1Q08" type 0 fixed SCSI 2 sd0(ahc0:0:0): Direct-Access 1042MB (2134305 512 byte sectors) (ahc0:1:0): "Quantum XP34300 81HB" type 0 fixed SCSI 2 sd1(ahc0:1:0): Direct-Access 4101MB (8399520 512 byte sectors) (ahc0:4:0): "ARCHIVE Python 28388-XXX 5.72" type 1 removable SCSI 2 st0(ahc0:4:0): Sequential-Access density code 0x13, 512-byte blocks, write-enabled The problem is that I've been getting device timeouts and some (automatic) reboots in the middle of the night due to who knows what. As of last night, I've gotten time outs on all three devices. sd0 did not get a time out, possibly due to it's not being mounted. Here is the series of entries from last night's adventure from /var/log/messages: Jun 18 04:38:19 tango /kernel: ahc0: target 4, lun 0 (st0) timed out Jun 18 04:38:19 tango /kernel: st0(ahc0:4:0): BUS DEVICE RESET message queued.

At this point the machine rebooted itself. Do I need to junk the controller and get a new one, or is there something I'm missing? I've only been working with FreeBSD for a few months so I'm no expert. -- Mike Loseke | If nobody else was violent, I could conquer System Administrator | the whole stupid planet with just a butter Verinet Communications | knife. -- Dogbert mike@verinet.com | ( DNRC Member )
