Further information: Also tried setting the IP address manually, but there is then also no usable LAN-connection. E.g. ping 192.168.6.50 Result: PING 192.168.6.50 (192.168.6.50): 56 data bytes ping: sendto: Host is down ping: sendto: Host is down But 192.168.6.50 is pingable from other hosts on the same network. On kernel releng/14.0-n265380-f9716eee8ab4-dirty everything worked fine. -- You are receiving this mail because: You are the assignee for the bug.
