--- Comment #2 from Konstantin Belousov <kib at FreeBSD.org> ---
(In reply to Neel Chauhan from comment #1)
It is wrong to use cpuid leaf 0x16 for frequency base, this is explicitly
stated in Intel SDM.  Also, I am even more curious about your machine config.

Please post verbose dmesg, as requested.
