my ok msg was too fast, after some time my video starts flickering and stay=
s=20
so and the PC is freezed up, disabling powerd and works stable

until it freeze cpu frequency shifting is done well

manually I can set all cpu speeds and seems to stay stable on each

must be related to X because I have some servers without X but=20
cpufreq+smp+powerd running absolutely stable

I found some msgs about the same problem with Gentoo and Debian and people =
say=20
the problem is with xorg and changing to xfree solved it for them but I=20
myself probably will not risk getting into a nightmare after the /usrX11R6=
=20
thing

I have no windows but fedora 7 on the same pc and works fine too,=20
kde's 'kpowersave info dialog' shows fine the cpu frequency shifting




=2D-=20
