The whole PC freezes, I can't switch to a TTY or SSH into it. Arch Linux, kernel 4.6.4. `journalctl -b -1` doesn't show anything unusual so it freezes before being able to log anything useful.\r\n\r\nPC 2: Intel Xeon X5670, arch linux, kernel 4.7.0 , it doesn't freeze but it does seem to break systemd. After 10-15 mins the connection will drop and reconnect. Eventually networkmanager seems to crash and doesn't list all the networks.  A bigger issue is that it seems to break systemd entirely. After the connection goes down this appears in dmesg:\r\n\r\n```\r\n[ 7876.783743] RTL871X: linked_status_chk(wlp0s29f7u2) disconnect or roaming\r\n[ 7878.808176] RTL871X:
