Hi,
Усть такая ситуация с powersave на буке:
$ powersave -t

]$ powersave -c
Speedstepping is not supported.

Видимо, с ядром 2.6.16 на этой машине следует использовать модуль
speedstep-centrino, а не acpi-cpufreq.
https://bugzilla.altlinux.org/show_bug.cgi?id=9495 - довесьте туда ещё
один образец вывода "cpuscan -v".

Огромное спасибо. После
modprobe speedstep-centrino
и
service powersaved reload
powersave -c
DYNAMIC
Как правильно закрепить успех?

Что-то у меня сейчас не получается подцепиться к багзиле. На всякий
