So again, a BIOS issue.
The machine has already the latest BIOS and it's unlikely that Toshiba will release a new version for old laptops. > OR you can configure udev so that ethtool disables WoL if you do not > want to pursue a EEPROM update through a BIOS update. I can configure udev but what about other people that install Linux and expect it to work (not drain battery after shutdown)?
