I guess ciphy(4) failed to report correct link state so watchdog handler was activated. Apparently we **NEED** a copy of the documentation for the PHY. :-( You can revert the PHY changes and use ukphy(4) until the issue is resolved. > > Probably a little more work on the patches is needed? > Yes, ciphy(4) should be educated to access magic registers. > I am offline for the next ten hours.
