In this case WoL works in S3 (multiple S3 cycles work) or after shutdown.
After reboot configuration MUST happen once again as it gets forgotten! (on both ACPI and RTL8169 sides - even though ethtool still shows previous WoL config)
A solution possibly would be to do all of the following:
- r8169 driver explicitely reconfigures WoL config it read during initialization
- r8169 enables ACPI wakeup for all PCI bridges above its card in PCI hierarchy if WoL is enabled
PS: forgot to mention in previous post, I'm running vanilla 2.6.24 with Rafael's patches 1-11 (ref in http://lkml.org/lkml/2008/1/27/292 ) and squashfs.
I found out more:
I need to toggle the wol state using ethtool AND enable item 7 (PCI2PCI bridge which enables root PCI node) using acpitool to get WoL working.
