Couple of thing I come accross when upgrading to 1.4, 
it would be nice to get them fixed for 1.4.1

1) The pr port-sun3/2727 seems to be still a problem.
I got the similar panic with unpatched 1.4. It seems 
to happen at least with qic-tapes that have soft 
errors while writing. I've now applied the patch to
my system to see if it helps (it helped with 1.3).

2) SCSI-poll timeouts

I needed to increase the 
int ncr5380_wait_phase_timo = 1000 * 10 * 300;	/* 5 min. */
timeout in /sys/dev/ic/ncr5380sbc.c to be able to format a scsi disk.

with NetBSD 1.3 and qic tapes I had to increase the
#define	 POLL_TIMO 50000       /* X100 = 5 sec. */
in /sys/arcg/sun3/dev/si.c to be able to retension QIC-tapes.
I'm not sure if it still needed with 1.4 since, I didn't
try to retension tapes with unmodified source. I can
check that out if needed.

3) ipf/ipnat

To get the ipnat working with 1.4 (and 1.3) I had to add
in the struct cdevsw cdevsw[] in /sys/arch/sun3/sun/conf.c

Thank's for the nice work!
