Just to be sure, are you able to check kern.timecounter.hardware on this one please? With the fix in v5 this should now use acpihpet or acpitimer (which are reasonable choices given the sync issues with tsc on this hw). (The kther machines you sent details for have enough to tell that they're working as expected). Thanks for the tests on these various interesting CPUs.
