After updating my FC6 from 2.6.20-1.2952 to 2.6.22.9-61, it seems I
started getting some error messages about TSC being disabled.
/var/log/messages had this with the old kernel:
Oct 26 21:52:02 localhost kernel: Total of 2 processors activated
(7317.20 BogoMIPS).
Oct 26 21:52:02 localhost kernel: ENABLING IO-APIC IRQs
Oct 26 21:52:02 localhost kernel: ..TIMER: vector=0x31 apic1=0 pin1=2
apic2=-1 pin2=-1
Oct 26 21:52:02 localhost kernel: checking TSC synchronization across 2
CPUs:
Oct 26 21:52:02 localhost kernel: CPU#0 had -1014760 usecs TSC skew,
fixed it up.
Oct 26 21:52:02 localhost kernel: CPU#1 had 1014760 usecs TSC skew,
fixed it up.
Oct 26 21:52:02 localhost kernel: Brought up 2 CPUs
Oct 26 21:52:02 localhost kernel: migration_cost=38
Oct 26 21:52:02 localhost kernel: NET: Registered protocol family 16
the new one says:

(7318.20 BogoMIPS).
Nov 4 19:24:28 localhost kernel: ENABLING IO-APIC IRQs

Nov 4 19:24:28 localhost kernel: Time: 19:23:47 Date: 10/04/107

Is this normal? Should I do anything about it?
Thanks
