>Description:
The perfmon(4) driver doesn't work on a kernel that has SMP enabled.
This should be documented in the man page (or better yet, fixed if
possible.)
>How-To-Repeat:
add this to GENERIC:

	options PERFMON
	options SMP
	options APIC_IO

make depend all install && reboot

run the perfmon example in /usr/share/examples/perfmon, it fails:

[root@hbo: /usr/share/examples/perfmon] ./perfmon 0
perfmon: open: /dev/perfmon: Device not configured
