Freebsd 2.2.5-RELEASE;  generic PCI NCR 53c81X SCSI;
Matshita and Toshiba external SCSI CD-ROMs;  DEC Multia Pentium 100

using the autopolled scsi cdrom driver
	device	cd0
cdroms are recognized on boot but invoking 
	mount -r -t cd9660 /dev/cdrom /mnt
hangs (hangs that process: uninterruptible wait on device).
(tried with various CDs in the drive).

FAQ mentions
	options	SCSI_DELAY=15
but this is standard in the 2.2.5-RELEASE generic kernel.

"man 4 cd" mentions optional syntax
	device	cd0	at scbus0 target 0 lun 0
for hardwiring the scsi id, but /usr/sbin/config calls this
a syntax error.

SCSI controller is recognized on boot as:
	<ncr 53c810 fast10 scsi> rev 2 int a irq 11 on pci0:6
and CDs show as
	(ncr0:0:0): "MATSHITA CD-ROM CR-504 ST23" type 5 removable SCSI 2
	cd0(ncr0:0:0): CD-ROM
	cd0(ncr0:0:0): CD-asynchronous.
	can't get the size
(the other CD was a toshiba in Sun external box;  same result)
