After much digging into the forums ans posts, here is the work-around to this
problem for this motherboard:
1. Removed the Trendnet (TEG-PCITXR) PCI LAN Card from the box. The motherboard
on-board LAN chip (Realtek RTL8111/8168B PCI Express Gigabit Ethernet
controller (rev 02) already supports Wake-on-LAN. Also, the Trendnet card has
some issues with PME (could even be motherboard).
2. Create a file /etc/init.d/wakeonlanconfig with the following:
#!/bin/bash
ethtool -s eth0 wol ug
echo enabled > /sys/class/net/eth0/device/power/wakeup
exit
3. sudo chmod a+x /etc/init.d/wakeonlanconfig
4. sudo update-rc.d -f wakeonlanconfig defaults
5. sudo /etc/init.d/wakeonlanconfig
6. cat /sys/class/net/eth0/device/power/wakeup
This should now show:
enabled
7. sudo pm-suspend
8. From remote box:
ping 192.168.x.x
Viola the system wakes up from suspend!
NOTE: Changing /etc/init.d/halt OR /etc/default/acpi-support OR
/etc/network/interfaces is NOT needed at all, as mentioned in some posts. But,
I did remove NetworkManager and removed all lines of code from:
/usr/lib/pm-utils/sleep.d/10NetworkManager
Hope this helps to keep the planet green.
