Thanks. I've noticed one thing there: QEMU seems don't enumerate i8254
timer device over ACPI. I was wondering if such systems exist, and now I
see one. Luckily there is enough other timers to work fine without it.

You may also try to check two HPET timers working in even more fresh
"legacy route" mode by adding to /boot/loader.conf:
hint.atrtc.0.clock=0
hint.attimer.0.clock=0
hint.hpet.0.legacy_route=1
