After noticing the problem went away in Safe Mode, and then figuring out
what Safe Mode actually does*, I've worked around the problem by disabling
the APIC device, which, I gather, forces FreeBSD to use the old-fashioned
IRQ timers. This fix will not work if you want to run an SMP kernel in
VMWare, I suppose, but I imagine there aren't too many people doing such a
thing. Anyhoo:
In /boot/loader.conf , add:
hint.apic.0.disabled=1
* All currently available documentation for FreeBSD Safe Mode, for those who
are interested, is apparently located here:
grep -A11 'bootsafekey @' /boot/beastie.4th
