Possible bug in eeepc-laptop.c - EeePC 900

[Fabio Comolli]

Hi.
I have an EeePC 900 running 2.6.34-rc1.

If I boot it on AC the cpu runs at full speed, 900MHz; if I boot it on
battery it runs only at 630Mhz. Plugging / unplugging the AC does not
change the cpu frequency. Only a reboot can change the situation.

I already tried to echo 0 or 1 to the
/sys/devices/platform/eeepc/cpufv file; no effects, even if the file
changes its value.

This is not a regression from 2.6.33: this behavior is also present in
that version.

Does this ring any bells? This is really annoying, especially when
trying to watch a movie on battery. Also 3D apps show a 30%
performance drop, as expected.

Regards,
Fabio
