Re: [gentoo-user] Suspend to ram: correct behavior?
Hi Daniel, Thanks for your response. I'll try to make some time to test your tips. You can also try booting a Fedora/Ubuntu/SuSE LiveCD, and see if with their kernel the same happens (given that suspend works on their LiveCD). If they manage to switch off the power to your USB-ports, that can give us a hint. That I can try, I still keep the Ubuntu (shame on me! :P) which I used to install Gentoo. Best regards, Damian.

I've booted with Ubuntu (damn it boots slow! :P) and after suspending the usb port was still yielding power. I guess it's better for me to find out if there actually is a way to prevent this. Best regards, Damian.

Hi Damian, please note, that I'm no kernel (or USB) expert - just guessing around from experience...

It was already enabled. Try disabling it :) If that does not help, unloading the USB and wireless drivers before suspend should do the trick. I added this line to /etc/hibernate/common.conf UnloadModules usb-ohci OHCI is nowadays just the USB-1-companion of EHCI, which is the driver for USB-2. EHCI listens on your USB-ports, and activated OHCI only when a USB-1-device is being connected. You should unload both. That is probably only possible, after unload all other usb-related modules :( But no luck. I don't know if I should add UnloadAllModules yes instead, just to be sure :D You could try that - if it works, begin removing modules selectively :) If you use sys-power/pm-utils for suspend hibernate, you can add kernel modules for automatic removal before suspend to SUSPEND_MODULES in /etc/pm/config.d/modules. I have sys-power/pm-utils installed, but no file named /etc/pm/config.d/modules. You can create it, and put into it a single line: SUSPEND_MODULES=iwl3945 mac80211 (my line ;) Anyway, I have USB support built in into the kernel, should I compile it as modules? That would make sense :) You can also try booting a Fedora/Ubuntu/SuSE LiveCD, and see if with their kernel the same happens (given that suspend works on their LiveCD).

Sounds like wake up from usb and wake up on lan is working. Either that or your devices did not go to sleep properly and are still awake.
