In the rest of my message - which you didn't quote - I stated that "the
error need not be v3.14-rc1 specific. But perhaps something changed in
v3.14-rc1 that makes it easier to trigger that error. I haven't
checked". (I didn't add that, in my experience, this message is not seen
at every boot.) So I'm basically advising Julian to double check whether
this is really a change in behavior between v3.13 and v3.14-rc1. But
perhaps Julian already did.
And I'm also telling Julian that, as far as I can tell, there's no
reason to print this message at KERN_ERR level because what subsequently
will happen is that an alternative calibration strategy is tried. So a
failure of fast TSC calibration is apparently not so severe. See
https://lkml.org/lkml/2012/9/24/221 . Is that analysis incorrect?
Thanks,
Paul Bolle
