Hi,
	I'm using FreeBSD-current (snapshot from Jan 3rd) which is configured
with both SMP and APIC_IO support. This version panics upon calling
acquire_timer0() (to modify the interrupt frequency of the 8254). On the other
hand, if the kernel is not configured as an SMP, then it works fine. The panic
reports some problem with some SMP lock - I can get more details if someone
is interested in looking at the problem.
