It seems the MAC locks up when PHY-probing results in 100MBit/s. Sometimes - at least intemediate it probes 100MBit/s on my TP-Link Switch, so I might end up without working ethernet. -- B.Walter <bernd at bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
