The sis driver supports at least two different types of cards. What does dmesg print for your card? I have only one type of NIC the sis driver supports and have only implemented support for this one: sis0: <NatSemi DP8381[56] 10/100BaseTX> port 0xac00-0xacff mem 0xdb001000-0xdb00 sis0: Silicon Revision: DP83816A > From userspace it > appears ready to set the NIC to wake (i.e. ifconfig > returns "will wake on: magic"), but the system ignores > magic packets and does not wake from FreeBSD. If the card type isn't a DP83815 or DP83816, this is a bug. The driver should not let you configure cards for WOL it has no support for. > Have verified that there is no reconfiguration of the > adapter as part of the FreeNAS shutdown scripts.

Here's a quick checklist (the first three are probably not causing your problem because you've verified that WOL works with Linux): Is the WOL cable plugged in properly (if needed)? Are BIOS WOL settings OK? Is ACPI enabled (in BIOS and OS)? Have you used "shutdown -p" to shut down the box? Using "shutdown -h" or "halt" and then turning the power off might not work (at least I've never tried this...) Does the card enter D3 sleep mode properly after the box shuts down, i.e. does a NIC LED stay on after shutdown? Do "wake" packets (e.g. magic packets) actually reach the box? To find out, I do: while true; do wol -h 10.42.42.255 <mac addr>; sleep 1; done and then if the box doesn't wake up I look at the NIC LEDS to check for periodic blinking of the tx/rx LED. Adjust the broadcast IP address to your network of course.
