My HP Surestore drives (on my i386) don't support tagged command
queueing. However, they claim they support it. :-)

Try a new kernel with `options SCSI_NCR_MAX_TAGS=0' in the config file.
If it works, that's the problem.

This will turn off tagged command queues for all drives. If there's
a way to set up a hint so that just a particular model of drive
will not use tagged command queuing, while others in the system
still do, I'd be interested in hearing about it.
