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 Akos _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
