I use a Fujitsu Siemens Amilo Xi 2550 (Intel Centrino Dual Core) and FC 9.
When KDE goes to some power save mode, the clock goes back afterwards,
e.g., the clock shows 11:18, but it is 11:48. Usually, the difference is
exactly 20 minutes or exactly 30 minutes or something like that.
There are some interesting lines in dmesg:
ENABLING IO-APIC IRQs
..TIMER: vector=0x31 apic1=0 pin1=2 apic2=-1 pin2=-1
checking TSC synchronization [CPU#0 -> CPU#1]: passed.
Brought up 2 CPUs
Marking TSC unstable due to: TSC halts in idle.
Clocksource tsc unstable (delta = -185554878 ns)
