Subject: suspend vs usb and PS/2 ports
Date: Wed, 30 Sep 2009 17:39:18 +0400	[thread overview]
Message-ID: <4AC35F86.20405@msgid.tls.msk.ru> (raw)

Hello.

I've several PCs here which are able to wakeup -
among others - from PS/2 and/or USB keyboard.
Here for testing I'm using PS/2 keyboard and
Asus M3A78-EM motherboard.

When I do poweroff from linux, the keyboard
stays powered up as it should (according to
the BIOS settings).  But when I do suspend,
keyboard is NOT powered anymore, and hence
the system can't be woken up from it but only
by using the power button.

This happens consistently for many kernel
versions.  To be fair, I don't even know if
there was any kernel which does not show this
behaviour: old versions was unable to do
suspend/resume cycle on this platform at all.

Any hints for this please?

Thanks!
