Incidentally, I have a patch for this issue, which is appended. Please test
and let me know if it helps (and WoL still works for you).
Thanks,

Subject: tg3: Do not call device_set_wakeup_enable() under a spinlock
The tg3 driver calls device_set_wakeup_enable() under a spinlock,
which causes a problem to happen after the recent core power
management changes, because this function can sleep now. Fix this
by moving the device_set_wakeup_enable() call out of the
spinlock-protected area.
