I'm not exactly sure if it's the USB ethernet dongle that's causing issues, but this never happens when I'm connected with wireless and I lose all network when this happens.
When I'm plugged in to the network using a USB hub -> USB ethernet dongle -> ethernet, I lose connectivity to the network, when I try to run: `sudo netctl stop ethernet` the command is non-responsive. Trying to kill the command doesn't work either. Any other `sudo` commands freeze. I can `su` to root, but I'm unable to `kill -9` any of those `sudo` processes. I can `netctl stop ethernet` but I can't `netctl start ethernet` again. What I have to do to fix this is do `halt -p`, which leaves me in a TTY with a blinking cursor until I smother the computer by pressing the power button for a few seconds.
This only happens occasionally so it's hard for me to debug and I want to get back to work so I just tend to reboot it forcefully and ignore it, but this week this has happened 3 times already, so I'm tired of it.
What logs should I check to debug this? What else can I do when I can't kill/restart processes using `kill`? Is this a known issue?
Thanks!
