2.4.22: APM Power-Off does not work

Hello!

Kernel 2.4.22 does not power of my HP omnibook 4150B (APM Bios 3.13)
(http://h20004.www2.hp.com/soar_rnotes/bsdmatrix/matrix31635en_US.html#BIOS).
With Kernel 2.6.0-test4-mm4 it works, but there suspend to disk does not work any more.

I tried with CONFIG_APM_REAL_MODE_POWER_OFF and without. The machine does not power off. It just stops after saying "Power off". When I press ctrl-alt-del afterwards, the kernel crashes in both cases.

Is there a patch for 2.4.22 around?

Regards, claas

This also applies to kernel 2.4.22-ac1.

Hi again,

after compiling all day long, the problem has disappeared and now it works fine with 2.4.22-ac1.

If someone is interested in the finally working kernel .config, i made it available for download here:
