I see, do you have any other ideas why it doesn't work on FreeBSD, while
works OOB on Linux 2.6 (reportedly) and definitely on Windows XP SP2?
Anything specific in our way of lapic/SMP handling?
BTW, I have noticed that we don't mark lapic page as noncacheable, which
seemingly required by the spec. I have made small change (3 lines), but
it doesn't help either.
P.S. I will bring the laptop to BSDCan so that I can let you or anybody
else play with it if it helps to fix the problem.
