[eranno]

using GA-Z68X-UD3H-B3 mono, sleep was working fine, not when I put to sleep it goes for 5-10 seconds, then wakes up.

Also has the problem with firewire guid is invalid.

I have the same problem and the same solution, but Wake on Lan is always checked again when I reboot. Any way to disable that or fix the problem?
