So could you please consider downgrading this message?

Yes, this will make regressions less visible, although I'm unsure we're
actually seeing a regression here. But I think that this is better than
scaring people about a situation they can't easily do something about,
if at all. Especially since fast TSC calibration failures, apparently,
can be worked around.
