nelsooon,

This should really be another thread as its not related to this topic.
Code:
Nov 4 15:07:20 localhost Clocksource tsc unstable (delta = -499087146 ns)

The delay is caused by the kernel evaluating the Time Stamp Counter (tsc) as a source of system time and finding it lacking.
This happens on CPUs that have clock speed control for power savings as the TSC counts from the (varable) CPU clock.

The TSC option is a kernel option - turn it off and rebuild your kernel
It seems be dependant on Pentum Classic in 2.6.24-rc1 your kernel may be dofferent.
