System: NetBSD anker.runit.no 1.4Y NetBSD 1.4Y (GENERIC.MP) #0: Tue May 9 17:22:48 CEST 2000 jarle@anker.runit.no:/usr/src/sys/arch/sparc/compile/GENERIC.MP sparc

>Description:

The si driver for sparc systems seems quite unstable.  My attempts at
using an Exabyte tape drive hooked up to the SCSI controller have led to
frequent crashes.  Granted, I've modified the si_match function so that
also Sun4m systems will be allowed to detect the presence of an si
adapter.

Some data:

o The configuration file used for the system is GENERIC.MP.

o The dmesg output is (some angle brackets removed):

#0 ok boot
