One more thing to check would be DMA channel settings. In software,
this parameter is contained the rightmost field of the file
/etc/conf/cf.d/mdevice (documented in mdevice(4)), in this
case on the "tape" line. For this particular device, the field
should be either 5 or 6, matching the setting in hardware. If
the software doesn't match hardware, or if that field is set to
"-1" (meaning device doesn't use DMA), this error message can
result.
