>Environment:
System: NetBSD 4.99.45
Architecture: i386
Machine: i386
>Description:
	Booting a kernel doesn't reach init. It stops with the following
	output from a serial console:
[..]     
crypto: driver 0 registers alg 11 flags 0 maxoplen 0
crypto: driver 0 registers alg 18 flags 0 maxoplen 0 
pad: requested 1 uni

	Sending a break didn't break into ddb.

	There are 3 dmesg outputs, which can be found on ftp.netbsd.org:~veego/
 
	dmesg.boot.4_99_31	working MP kernel 4.99.31
	dmesg.boot.4_99_45	broken MP kernel 4.99.45
	dmesg.boot.non_mp	working non MP kernel 4.99.45
 
	The 4.99.45 was updated 25-Dec-2007 around 14:00 UTC.
	The 4.99.31 was from arouund 05-Oct-2007. 

	Btw, the 4.99.45 MP kernel output is a little strange:
		-com0: ns16550a, working fifo
		+com: ns16550a, working fifo
	Why is the 0 missing from the MP kernel output?
>How-To-Repeat:
	Boot a MP kernel on a gigabyte K8NSC mainboard.
