I have a Seagate DDS-4 tape drive: sa0 at sym0 bus 0 target 3 lun 0 sa0: <SEAGATE DAT 9SP40-000 912L> Removable Sequential Access SCSI-3 device sa0: 40.000MB/s transfers (20.000MHz, offset 16, 16bit) It's attached to a Tekram DC390F SCSI card: sym0: <875> port 0xc000-0xc0ff mem 0xe9004000-0xe90040ff,0xe9006000-0xe9006fff irq 20 at device 0.0 on pci7 sym0: Tekram NVRAM, ID 7, Fast-20, SE, parity checking sym0: [ITHREAD] Occasionally, whenever I open sa0 for reading (typically when Amanda starts flushing backups to tape), the system resets. I don't mean that the kernel panics or anything; I mean that within a second or two I'm looking at a POST screen. I'd been having this problem for a while, but recently upgraded literally every other piece of hardware on the system. The card and drive were the *only* components carried over to the new system, and I even swapped out the card for a duplicate I had stored away. Is it possible that the drive itself is triggering the reset? I'd find that a little unlikely, but am certainly not an expert on the matter. Alternatively, has anyone had that sort of problem with drives attached to that card? -- Kirk Strauser
