cpufreq and lapic timer

[Andriy Gapon]

Nate, guys,

in 6.1 we by default use LAPIC timer now and I wonder what can affect
its frequency. The reason I am asking is that it seems that it starts to
work slower if I use my nf2fsb cpufreq driver and change FSB (and thus
CPU_ frequency.
Some data:
$ date ; sleep 300 ; date
Fri  9 Jun 2006 19:16:41 EEST
Fri  9 Jun 2006 19:22:55 EEST
$ bc
scale=5
300 / 374
.80213
133 / 166
.80120

I.e. it seems that LAPIC timer runs slower by the same factor that
frequency is changed.

Any recommendations ? ideas ?
Thank you.
