suspend works until core pm_test, but the still fails

["Ákos Maróy" <akos@maroy.hu>]

Hi,

I'm still trying to make power management work on my HP Envy 15.

I'm experimenting with unloading as many modules as possible, testing
the suspend feature using various levels of /sys/power/pm_test

I managed to get the number of modules as low as these:

Module                  Size  Used by
binfmt_misc             7454  1
bnep                   11287  2
btusb                  12729  2


then I was going through these steps;

echo freezer > /sys/power/pm_test
echo mem > /sys/power/state
echo devices > /sys/power/pm_test
echo mem > /sys/power/state
echo platform > /sys/power/pm_test
echo mem > /sys/power/state
echo processors > /sys/power/pm_test
echo mem > /sys/power/state
echo core > /sys/power/pm_test
echo mem > /sys/power/state

and all these worked fine - meaning that I got back to the console
screen. I also ran dmesg, and didn't see anything suspicious.

but, when I do:

echo none > /sys/power/pm_test
echo mem > /sys/power/state


the machine will still hang :(


what am I doing wrong?

this is all on a 2.6.32.9 kernel
