Pentium-M in compaq evo n620c notebok, cpufreq active: pavel@Elf:~$ dmesg | grep tick dyn-tick: Found suitable timer: tsc dyn-tick: Registering dynamic tick timer v050610-1 dyn-tick: Maximum ticks to skip limited to 13 dyn-tick: Timer not enabled during boot pavel@Elf:~$ Ouch, even system time seems to go slower.
