	Probably the best place to email messages like this is port-sparc,

	I'm no SCSI expert, but you mightr want to try booting with a
	1.2.1 kernel, or even a kernel from the latest snapshot
	(ftp.netbsd.org/pub/NetBSD/arch/sparc/...).

	Bear in mind using a 1.2 userland with a snapshot kernel is
	likely to cause ps & friends to break, but it should be fine for
	test8ing if the problem has been fixed.

	If these fix the scsi errors then you might want to upgrade to
	1.2.1, or the snaphot.

	Alternatively if you have a specific kernel config feel free to
	mail it to me & I'll build a kernel from the latest -current
	source.
