Just filling in with extra context, I did say "FWIW" ;) I don't use 5.4 nor do I understand the consequences of bad hpet well enough to comment on risk vs reward here. By consequences of bad hpet I mean whether its going to impact anything beyond the tsc -> hpet fallback (which doesn't impact <5.13).
