well, after a long time testing, the microp 4421-07:
da0: <MICROP 4421-07 0329SJ 0329> Fixed Direct Access SCSI2 device
has serious problems with tag queuing... the only way I was able to
get this drive to work reliably was to turn of tags completely... does
anyone have a drive with a different firmware that does do tags?
if no one does, I'll just commit the attached patch....
