--- Comment #4 from Konstantin Belousov <kib at FreeBSD.org> ---
Non-verbose dmesg is not useful for a diagnostic.

>From the figure of the things I suspect that your issue might be failing 8254
piece of the chipset.  Can you confirm or deny that booting non-patched 10.3
kernel report 4GHz frequency ?

Another thing to try is to change both timecounters and eventtimers to HPET:
sysctl kern.timecounter.hardware=HPET, kern.eventimer.hardware=HPET and see
what ntpd thinks about machine.
