There is a em card in the machine and the motherboard msk card. The most recent update of the msk card seems to crash the system at startup.. so I took it out of my load config.. have not played with it yet.. Previously I could ping the msk net.. and the machine would wakeup.. now that I don't have the msk card.. guess what.. pinging the em0 card DOES NOT wake the machine up.. I bet there is some foul-up on the motherboard causing it to not deliver interrupts until another one (on the mother board) comes in... oh well..
