[Bug 30570] Re: CPU usage very high with no running tasks using it

[Micksa]

*** This bug is a duplicate of bug 30557 ***

My inspiron 6000 (Pentium M) exhibits this problem on at least
2.6.15-23-686 and 2.6.15-25-686, and the max_cstate fix:

echo 1 > /sys/module/processor/parameters/max_cstate

Fixes it.  As an added bonus, with -25 I get some weird timing problems
(beeps sound for different lengths, the "zooming" box that animates when
you click a gnome panel icon is erratic, etc), which are also fixed with
the above command.
