Am running -CURRENT right now, and am wondering if there are any known
problems/caveats with either one of:
ahc0: <Adaptec 2910/15/20/30C SCSI adapter> port 0xc400-0xc4ff mem 0xef000000-0xef000fff irq 19 at device 9.0 on pci0
aic7850: Single Channel A, SCSI Id=7, 3/255 SCBs
-or-
da0 at ahc1 bus 0 target 0 lun 0
da0: <SEAGATE ST36530N 1281> Fixed Direct Access SCSI-2 device
da0: 20.000MB/s transfers (20.000MHz, offset 15), Tagged Queueing Enabled
da0: 6208MB (12715920 512 byte sectors: 255H 63S/T 791C)
ch0 at ahc0 bus 0 target 4 lun 1
ch0: <DEC TZ Media Changer 851A> Removable Changer SCSI-2 device
ch0: 5.000MB/s transfers (5.000MHz, offset 15)
ch0: 7 slots, 1 drive, 1 picker, 0 portals
The reason I ask is that I just picked up the changer/dlt, slap'd the
above card in, and am working with amanda. This morning, I was running
'amcheck' on it, and it generated the following error(s):
Oct 28 13:10:16 thelab /boot/kernel/kernel: (sa0:ahc0:0:4:0): tape is now frozen- use an OFFLINE, REWIND or MTEOM command to clear this state.

yet I can manipulate everything from the buttons on the front no problem.
I missed the 'use an OFFLINE ...' message the first time through, so am
going to reboot to see if I can re-create the error(s), but am wondering
whether or not this is maybe something that ppl have experienced with
either the controller/tape or changer, and is something I should be
expecting ...
Thanks ...
