Yes, tagged queueing is off. It still uses NetBSD-current from just
before the new ahc was ported to NetBSD, so it uses the old driver.
Wanted to wait for a while untill the new driver stabalized and
haven't had time to decently upgrade the machine to more current (was
actually hoping for 1.5 around this time). Another note, the machine
hosts *two* adaptec SCSI controllers. Can that cause trouble like this?
