WOL in the BIOS causes spontaneous power ups after shutdown

In order to support WOL, my Asus H87I-Plus requires an option set in the BIOS (Onboard>APM>Power on by PCIE). When I have this enabled, I can indeed start the machine using the wol magic packet, but there is an undesired side-effect: about 25 % of the time I shutdown the machine, it stays shut off for about 5 sec and then turns back on all by itself. If I disable the option in the BIOS, this does not happen... but I am unable to use wol.

Anyone run into this issue before? Motherboard BIOS issue?
 
Are you running the current BIOS?

Have you cleared the CMOS and tried again?
 
Update - Latest BIOS 1005 does not fix this problem and 14 emails between myself and the people at Asus who barely speak English have not been fruitful.
 
I've been looking at this mobo, but there are a few issues keeping me from pulling the trigger.
This has been a persistent issue on the NAS and HTPC forums.
No BIOS update has resolved it yet.
I have 5 ssd's waiting for a new build, vMware ICM class has started.....I may just get a Synology box and call it good.
 
This is the only issue stopping me from recommending the board at present. It is fine otherwise, but if you need WOL it is a critical one. Can you post a few links to the posts to which you refer [i.e in the NAS and HTPC forums]? Thanks you.
 
Booting into windows 7 and then shutting down from there does not exhibit this behavior. It seems to be something unique to Linux...
 
It's just internet noise waking the machine. Leave BIOS in default.

Under Advanced settings for network adapter , Enable "Magic Packet" but disable “Wake on pattern match”.

In XP use, Enable "Allow this device to bring the computer out of standby" but "Only allow management stations to bring the computer out of standby". Win7 has similar setting.
 
I just tested it under windows 7 to see if it was a Linux problem, or universal. This machine runs Linux.
 
An update: this is a BIOS bug but there is a work-around. I have been testing several systems (Z77 and H97-based) after I disabled all references to 'xHCI' as it pertains to USB settings[1]. I also enabled wake on keyboard[2]. And finally, I disabled EuP 2013 which affects wattage in power off mode. For over 2 months now, I haven't observed an unintentional wake-up with 'wake on PCIe' enabled in the BIOS.
