WoL to this system can not do anything.

Playing with grub's cmdline arguments acpi=off, acpi=ht, pci=noacpi, acpi=noirq, pnpacpi=off, noapic, nolapic - do nothing. Same results.
Playing with BIOS PM options APCI, APM, Legacy, Disabled - do nothing. Same results.

Same results on Openwrt 15.05.1 x86-geode.

But works perfect on Openwrt 14.07 x86-generic.
