Hi,
$this->bbcode_second_pass_quote('', 'p')acket_write_wait: Connection to 192.168.0.31 port 22: Broken pipe
Weird. (This error is at the command line on the client machine ssh'ing into the RPi2, of course.) This usually means the network connection was broken/dropped. When I connect to a client machine at a remote site and leave the connection idle for a long time I see this sometimes. But you're connecting locally.
The Avahi stuff is auto address assignment, etc. It's never caused me any problems under Arch besides being an occasional nuisance when I have a network config problem. Not sure why systemd is starting org.freedesktop.Avahi.service except that dbus may be requesting it(?). On my ALARM installations this isn't getting started according to the journal, but I'm not running a full desktop or other stuff.
Wish I could be of more help. Reflashing with the original image sounds like a good place to start
