Well not specifying "cpuidle" and "cpufreq=xen" on the xen boot line in grub,
should not enable them for the clocksource=pit case right ?
I did exactly that on this boot.
(from
http://wiki.xen.org/wiki/Xen_power_management#PIT_as_broadcast_timer_source_.28clocksource.29
i read:
Currently, by default cpuidle will be selectively disabled while HPET is not
available.
So for system only with PIT, the cpuidle is still disabled by default.
If user really wants cpuidle feature with PIT as broadcast source, please
specify 'cpuidle' grub option.
