Looks fine. Here is mine:
sa0 at ahc0 bus 0 target 6 lun 0
sa0: <HP C1557A U812> Removable Sequential Access SCSI-2 device
sa0: 10.000MB/s transfers (10.000MHz, offset 15)
[...]

ch0: 10.000MB/s transfers (10.000MHz, offset 15)
ch0: 6 slots, 1 drive, 0 pickers, 0 portals
With a tape in the drive, what does the command "mt -f /dev/nrsa0 status"
show?
On my HP DAT40x6i changer (the DDS-4 version) my DIP switches are set
as:
1 2 3 4 5 6 7 8
0 1 0 1 1 1 1 1
And I'm pretty sure these are the same settings we have on the
24X6i. (I had just this evening yanked a busted Seagate Scorpion DDS-4
drive, so I can actually see the switches! Talk about timing. :))

I agree, this looks like a hardware problem.
Have you verified your SCSI stuff: jumpers, termination, cable
lengths, etc.?

I've never used the 4.0-RELEASE stuff, if possible, can you try
something newer like 4.3?
