Hello, I have a system whose motherboard (Supermicro X5DP8-G2) comes with a builtin Intel PRO/1000 MT Dual Port Server Adapter (82546EB). The system is running RedHat Linux kernel 2.4.18 and the NIC driver is e1000 version 4.4.12. I am wondering if it is possible to disable WOL on this NIC. From looking at the driver code, it's clear that the function e1000_suspend() is the one that sets up the NIC for what it should do in response to a WOL event. The driver writes WUC and WUFC registers with a 0 and then calls pci_enable_wake() for state 3 and 4 with a 0. However, this does not seem to disable WOL. Namely, even if I force execution of this code path, once the system shuts down and a magic packet is sent to the NIC, the system will come up again. I added some debugging code that dumps contents of the WUC register before and after it is written with a 0 in the "disable WOL" code path. It turns out that WUC seems not to respond to this write. Specifically, WUC is set to 0x4 (that's the E1000_WUC_PME_STATUS bit). Can anyone shed some light on this?
