The video BIOS is messing with the 8254. It may be worth a shot

Try putting this in /boot/loader.conf:
this fixes the problem without any hardlocks.
I am assuming you are booting without ACPI? Usually the ACPI timer
is used if you boot with ACPI and this problem doesn't occur. If ACPI
doesn't work for you it may still be possible to boot with ACPI just
to get at the timer, but with most of the features disabled. 'man acpi'
tells you how to disable certain features.
i am always booting with ACPI enabled. but still it uses the i8254 timer.
my guess was in SMP environment LAPIC timers are used.
