I have an Exabyte EXB-8200 on one of my boxes which has been giving
me faithful service under FreeBSD for ages.

I upgraded that machine to 3.0-RELEASE last night, though, which
included a switch to the CAM SCSI drivers.  Since then, my Exabyte
hasn't been working.

ahc0: <Adaptec aic7880 Ultra SCSI adapter> rev 0x00 int a irq 11 on pci0.9.0
ahc0: aic7880 Wide Channel A, SCSI Id=7, 16/255 SCBs
   [ ... ]
sa1 at ahc0 bus 0 target 6 lun 0
sa1: <EXABYTE EXB-8200 425A> Removable Sequential Access SCSI1 device
sa1: 3.300MB/s transfers

No matter what I try to write to it, it reports that it has reached
the end of its media -- dd says:

    atdot# dd if=/dev/zero of=/dev/nrsa1 bs=1024
    dd: /dev/nrsa1: end of device

dump gives me a change volume request before writing its first block,
tar reports that it has written 0 of 10240 bytes and errors out.

Are there any known problems with EXB-8200's?  Do I need to change
any jumper settings to make my drive work?  Do I need a particular
PROM revision?  Doctor, will I ever play the piano again?

Thanks in advance,

    - mark
