I'm attempting to enable netconsole on my home PC, however encountering some trouble with my bridged LAN and Wi-Fi.If I don't specify an interface name, it fails as follows:$ sudo modprobe netconsole netconsole=6666@192.168.0.1/,6666@192.168.0.2/A0:F3:C1:FF:4C:70 modprobe: ERROR: could not insert 'netconsole': No such devicedmesg output:netpoll: netconsole: local port 6666netpoll: netconsole: local IPv4 address 192.168.0.1netpoll: netconsole: interface 'eth0'netpoll: netconsole: remote port 6666netpoll: netconsole: remote IPv4 address 192.168.0.2netpoll: netconsole: remote ethernet address a0:f3:c1:ff:4c:70netpoll: netconsole: eth0 doesn't exist, abortingnetconsole: cleaning upIt tries to look for eth0 and fails, most likely because systemd renamed it to enp9s0. If I specify the new interface name explicitly:$ sudo modprobe netconsole netconsole=6666@192.168.0.1/enp9s0,6666@192.168.0.2/A0:F3:C1:FF:4C:70modprobe: ERROR: could not insert 'netconsole': Device or resource busydmesg output:netpoll: netconsole: local port 6666netpoll: netconsole: local IPv4 address 192.168.0.1netpoll: netconsole: interface 'enp9s0'netpoll: netconsole: remote port 6666netpoll: netconsole: remote IPv4 address 192.168.0.2netpoll: netconsole: remote ethernet address a0:f3:c1:ff:4c:70netpoll: netconsole: enp9s0 is a slave device, abortingnetconsole: cleaning upOK, so it doesn't like that enp9s0 is part of a bridge. Let's try it with the bridge:$ sudo modprobe netconsole netconsole=6666@192.168.0.1/br0,6666@192.168.0.2/A0:F3:C1:FF:4C:70 modprobe: ERROR: could not insert 'netconsole': Unknown error 524dmesg output:netpoll: netconsole: local port 6666netpoll: netconsole: local IPv4 address 192.168.0.1netpoll: netconsole: interface 'br0'netpoll: netconsole: remote port 6666netpoll: netconsole: remote IPv4 address 192.168.0.2netpoll: netconsole: remote ethernet address a0:f3:c1:ff:4c:70netpoll: (null): wlp6s0 doesn't support polling, abortingnetconsole: cleaning upLooks like it tries to set up all interfaces that are part of the bridge, and fails at the Wireless interface.Does a solution exist?
Linux netconsole with bridged interface
