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:
Nov 4 19:24:28 localhost kernel: Total of 2 processors activated (7318.20 BogoMIPS).
Nov  4 19:24:28 localhost kernel: ENABLING IO-APIC IRQs
Nov 4 19:24:28 localhost kernel: ..TIMER: vector=0x31 apic1=0 pin1=2 apic2=-1 pin2=-1 Nov 4 19:24:28 localhost kernel: checking TSC synchronization [CPU#0 -> CPU#1]: Nov 4 19:24:28 localhost kernel: Measured 4105718628 cycles TSC warp between CPUs, turning off TSC clock. Nov 4 19:24:28 localhost kernel: Marking TSC unstable due to: check_tsc_sync_source failed.
Nov  4 19:24:28 localhost kernel: Brought up 2 CPUs

Nov  4 19:24:28 localhost kernel: NET: Registered protocol family 16


Is this normal? Should I do anything about it?

Thanks
