i made some more cpu over-clocking tests of the live image on my 1101ha.
1101ha has six over-clocking modes that can be set in bios: 05%, 10%,
15%, 20%, 25% and 30%. more matter what mode i set in bios before boot,
the contents of the files below is always the same after boot:
user at debian:~$ more /sys/devices/platform/eeepc/available_cpufv
0 1 2
user at debian:~$ more /sys/devices/platform/eeepc/cpufv
0x300
when i then shutdown live image and check over-clocking setting in bios,
it is always back to the lowest value 05%, no matter what it was before
i booted the test image.
during boot, i see on console:
Setting super hybrid engine according to configuration (AC) ...
so i guess that this is what re-writes the initial value in bios. if
so, it should not use the lowest value when on AC power.
one more thing: if i set over-clocking to 30% in bios and then boot live
image, kernel always crashes after printing the above text. the
backtrace refers to acpi related stuff.
