Should be...
Let me get this straight - before this commit, the messages don't appear, yes?
Looking at the hunk and AFAICT, it checks APIC_LVTTHMR[VEC] and it did bail out if something was there != 0 before.
With this check removed, we go and actually init.
So I can imagine BIOS programming stuff in it already and us not even initializing thermal throttling due to that. And this commit actually *fixed* it on baremetal too.
But that would be crazy, BIOS would never do something like that?!</sarcasm>
Tony?
