This is not good. It probably means that it actually tries to set up the NIC
for waking up the system, but something broke _that_ for you.

FWIW, I tried it on my test machine with sky2 and it worked.

Can you try:

# ethtool -s eth0 wol g
# echo devices > /sys/power/pm_test
# echo mem > /sys/power/state
(this should wait for 5 seconds and return to the command line)
and see if the machine hangs during this operation?

Please also attach the boot log from your system.

Thanks,
Rafael
