Do you know the official NIC product name e.g Pro/100B. I need to identify the LAN Controller. There are differences between 557 (not sure if 557 can do WOL), 558 and 559 how they ASSERT the PME# signal. Even the same chip have differences between steppings.
I suspect that PME# is not being DEASSERT after the Wake-up packet is received - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
