Hello, I have a problem with WOL(Wake-On-Lan) and suspend mode.

In my labatory, we use ASROCK main board B75M .
We tested on ubuntu 12.10.

However, WOL and suspend mode does not work.

For, example

When we use 'pm-suspend' , to target pc, it works well without WOL

But, when we use 'pm-suspend' after WOL, it does not work properly.
The target pc does not go into suspend mode. it rewakes.

We don't know how to solve it.

We did everything we can do.(driver update, change lancard, change graphic card, change OS , Bios update and so on..)

This problem makes us frustrated....

Thank you for reading my poor english.
Hope anyone can help me on this .
Thanks!!
