If you turn off WOL in the BIOS, does the NIC still stay fully
powered?  We discovered a bug in the Linux kernel e1000 drivers that
will hork the firmware and the only fix was to remove the power cord
and do a cold boot of the system.  It's especially annoying when the
chassis you need to yank power on is a single chassis with 2 seperate
systems sharing a power supply, and you can't power off the other
half!

I'm wondering if we could avoid yanking power to these systems by
shutting off WOL ?
