Thanks, Michael. After digging some more into it, I've found that the
problem is in tg3_power_down_phy() routine. Apparently 57780 PHY
is not handled properly. If tg3_power_down_phy() is not invoked from
tg3_set_power_state(), the problem is not reproducible anymore. I don't
have enough information about NIC internals to dig further.
Felix.
