Aside of that this leaves the HPET in a half broken state. HPET is not only
used as a clock event device it's also exposed by HPET device. So no, if we
figure out that HPET is broken on some platforms we have to blacklist and
disable it completely and not just duct tape the place which exposes the
wreckage.
