I used to have an Adaptec 2940UW in this machine, but I now have a: sym0: <895> port 0xd800-0xd8ff mem 0xefffe000-0xefffefff,0xefffff00-0xefffffff irq 11 at device 13.0 on pci0 sym0: Tekram NVRAM, ID 7, Fast-40, LVD, parity checking This attaches: sa0 at sym0 bus 0 target 3 lun 0 sa0: <HP C1533A A708> Removable Sequential Access SCSI-2 device sa0: 10.000MB/s transfers (10.000MHz, offset 31) sa1 at sym0 bus 0 target 9 lun 0 sa1: <HP C5683A C908> Removable Sequential Access SCSI-2 device sa1: 40.000MB/s transfers (20.000MHz, offset 31, 16bit) da1 at sym0 bus 0 target 1 lun 0 da1: <QUANTUM ATLAS IV 18 WLS 0808> Fixed Direct Access SCSI-3 device da1: 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing Enabled da1: 17522MB (35885168 512 byte sectors: 255H 63S/T 2233C) da0 at sym0 bus 0 target 0 lun 0 da0: <SEAGATE ST39173W 6244> Fixed Direct Access SCSI-2 device da0: 40.000MB/s transfers (20.000MHz, offset 15, 16bit), Tagged Queueing Enabled da0: 8683MB (17783240 512 byte sectors: 255H 63S/T 1106C) Mounting root from ufs:/dev/ad0s1a cd1 at sym0 bus 0 target 5 lun 0 cd1: <RICOH MP6200S 1.00> Removable CD-ROM SCSI-2 device cd1: 3.300MB/s transfers cd1: cd present [1 x 2048 byte records] ... now sa1 is an external drive that I sometimes take somewhere else. I've found that camcontrol rescan on this card can wedge the scsi bus for a number of seconds. This didn't happen on the adaptec, so I'm assuming that this isn't normal behavior. When things return to normal, the rescan is successful, but the 30ish second wait isn't pleasant.
