Du ved godt at der er hjælp til de fleste kerne options, ikke?

------

The power Management Timer is available on all ACPI-capable,
in most cases even if ACPI is unusable or blacklisted.

This timing source is not affected by powermanagement features
like aggressive processor idling, throttling, frequency and/or
voltage scaling, unlike the commonly used Time Stamp Counter
(TSC) timing source.

So, if you see messages like 'Losing too many ticks!' in the
kernel logs, and/or you are using a this on a notebook which
does not yet have an HPET, you should say "Y" here.
