>Description:

	5.0R generic kernel with SMP enabled

	I get:

	xl0: watchdog timeout
	xl0: watchdog timeout
	xl0: watchdog timeout

	and xl0 is completle unusable.

	If I boot GENERIC from CD this does not happen but
	also GENERIC does not seem to be SMP enabled


>How-To-Repeat:

	take 5.0R disc1, install incl. src

	copy GERNERIC to mygenericsmp.conf

	enable
	# To make an SMP kernel, the next two are needed
	options         SMP                     # Symmetric MultiProcessor Kernel
	options         APIC_IO                 # Symmetric (APIC) I/O

	make buildkernel KERNCONF=mygernericsmp.com
	make installkernel KERNCONF=mygenericsmp.conf

	reboot... and watch

>Fix:

	N/A
