Howdy,

	Just built a kernel from today's sup and it blew major chunks
	right at boot, backtrace and misc to follow.

	Anybody else have problems on sun4c? Specifically 1+ with 32M
	and 1 SCSI disk. March 3'rd code works fine.

------------- Crash and burn follows:

ok reset
SPARCstation 1+, No keyboard.
ROM Rev. 1.3, 32 MB memory installed, Serial #61207.
Ethernet address 8:0:20:a:57:fe, Host ID: 5300ef17.
