Having issues getting hardinfo to work on Xenial

[EdLesMann]

Greetings,

I skipped the hardinfo as it isn't needed and I did a lot of the testing
procedures. Everything worked as expected except for middle clicking
(reported that already).

Well, I just discovered another issue. Starting out in the dock,
everything works as it should. Unplug from the dock and everything
continues to work. Plug back into the dock, and complete freeze with a
black screen. Hard reset required.

On reboot I didn't see anything in particular that looked interesting in
the logs for why the crash.

What information should I provide and to whom?

Thanks!
