Bog-standard April 12th snapshot (kernel & userland) on an SS2+Weitek:

netbsd4me:1:21 % uname -a
NetBSD netbsd4me 1.1B NetBSD 1.1B (GENERIC_SCSI3) #10: Thu Apr 11 16:02:07 MET
DST 1996     pk@neon:/usr/src/sys/arch/sparc/compile/GENERIC_SCSI3 sparc

As soon as I pressed "eject floppy", I got:

fdc: spurious interrupt: state 7, istate=3
fdc: spurious interrupt: state 10, istate=2
panic: fdcintr: spurious interrupt can't be cleared
Frame pointer is at 0xf81176e8
Call traceback:
	pc = f80f9918 args = ( 400, 90000fe7, 0, f8117808, f8649400, f80c1740,

	pc = f8022af0 args = ( 104, f811dc00, 1, f8117870, f8c49170, f8135000,

	pc = f803c7c4
	pc = f80f18c0
	pc = f80c8a38
	pc = f8007950
	pc = f8??????

The panic happened immediately after the 2 "spurious interrupt" messages
splattered on my screen.
