I have a

(aha0:3:0): "WANGTEK 6130-FS 3.04" is a type 1 removable SCSI 2
st0(aha0:3:0): Sequential-Access density code 0x13,  drive empty 

It works fine with dump, tar, dd, cat, but panic's as described above
with I run restore.

I'm running a week old -current.

By the way, the drive is not empty.
