Hard to tell without knowing what actually went wrong. It wasn't
very long ago that we had to fix an issue where iirc a machine
wouldn't even boot because of some strange state firmware put
the TSCs in. We were able to work around this, such that
"tsc=unstable" wouldn't be needed. So while there may indeed be
some oddity with what firmware does, there may also be a way to
work around this. But I guess it would take someone debugging
this on an affected system...
