Subject: WoL and r8169
Hi,
I've got an issue with Wake on Lan on my r8169 equipped ASUS M2A-VM HDMI
motherboard. For all I can tell, I've done what it takes to enable WoL ("Wake
on PCI/PCIe" is enabled in the bios), but it fails to restart.
checking ethtool, wol sohould be enabled:
tv ~ # ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: MII
PHYAD: 0
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: pumbg
Wake-on: g
Current message level: 0x00000033 (51)
Link detected: yes
The little documentation I've found suggests that these are relevant to:
tv ~ # cat /proc/acpi/wakeup
Device S-state Status Sysfs node

PCE6 S4 disabled
PCE7 S4 disabled pci:0000:00:07.0
PCE8 S4 disabled
UAR1 S5 disabled pnp:00:08
I've tried setting them all to enabled, to no avail.
Futher investigations suggests that the sysfs interface and the device tree
need to be told to do the right thing:
Out of the box, I get:

I've gotten the impression that my eth controller lives behind a pci bridge and
behaps a pci bus, neither of which are enabled (the controller _does_ appear to
be enabled!). However, enabling the bridge and the bus (and all other devices)
of the above devices in /sys, still leaves me without WoL.
Am I missing something obvious here? Enabling USB stuff in /sys got wake on USB
working ok, so the ethernet stuff should be similar, I'd assume.
The two leds by the wire go black when the machine suspends, should they be
lit?
I'm pretty certain the WoL packet is coming to the box (tried both network
broadcast and unicast with a prepared arp cache at the sender).
Any insight in the appreciated.
