Comment # 7 on bug 67800 from Kertesz Laszlo

Last night i rebooted and re-activated C6 in the BIOS. Reactivated dpms (turn
off display completely after 4 minutes).

It the morning (~7 hours of idle time) the computer works as expected. So it
seems that those patches  solved this issue. I will test it further for anothey
day.

As a sideline, sleep state C6 enabled in the BIOS (versus disabled) lowers the
idle temperature of the APU by 2-4 C.
