Ok, please try latest re(4) in HEAD. If that does not change the
behavior, give attached patch spin and let me know whether it makes

under certain conditions but if you do not remove UTP cable that
wouldn't happen. I have to verify whether it can really trigger
watchdog timeouts and it takes more time on my side.
