OK, so my guess would be a driver issue.  What driver is this, igb?

Yes it does, I checked two machines earlier today, both work.

Can you enable dynamic debug in device_pm.c and send a dmesg output
with that covering a suspend-resume cycle?

Thanks,

Hmm.  That also is there in my venerable Thoshiba Portege R500 which
wakes on LAN with 4.13-rc4.  So the driver is off the hook I guess.

Thanks for all the help.

I now realized what was going on: I had badly inserted ethernet
cable; machine just connected to wifi, and everything worked... except
wake on LAN.

Sorry for the noise,
