Suspend and wake on lan

Suspend and wake on lan

[Rob Walker]

Hi,

I'm having some trouble getting wake on lan to work after the computer is 
suspended.  Wake on Lan works if I shut down the computer normally (i.e. it 
powers up again when I send the magic packet), but doesn't wake up when I 
suspend the computer to disk and then send the magic packet.  I ensure that 
wake on lan is enabled before suspending by running `ethtool -s eth0 wol g`.

The computer is an AMD Athlon, using a Gigabyte GA-71X motherboard with VIA 
KT400 chipset.
The on board network chip is a RealTek RTL8139, using the 8139too driver.

I've tried the kernel from debian testing (2.6.18) and a hand built 2.6.19.1 
kernel, both with the same results.  

I've tried uswsusp and the in-kernel suspend, again both with the same 
results.

Can you help?

Regards

Rob

Hm, not really, but I think the 8139too's suspend routine does something
that disables WOL.

Please try to contact the author/maintianer of the driver.

Rmmod 8139 driver before suspend and use shutdown, not platform, mode?
