This seems to be similar to the problems reported here: http://lkml.org/lkml/2007/11/19/345 but I am not as far as I am aware using the ondemand governor. > cat /proc/acpi/processor/CPU0/info processor id: 0 acpi id: 0 bus mastering control: no power management: no throttling control: no limit interface: no What is suspisious is "Clocksource tsc unstable". Dump from dmsg follows. Any light people can shed on this much appreciated. Cheers, Erik [ 80.215847] Marking TSC unstable due to: cpufreq changes.
