Hi,
I have a dell 7490 with its docking station.
I've been working for several months on Ubuntu 19.04 and things were pretty solid.
I upgraded to 19.10 last week and since then every time the computer goes to suspend the thunderbolt usb devices no longer works- which means for me - the keyboard and mouse. the monitor, however still works.
What I need to do is disconnect the docking station, remove the authorized devices, then re-connect, re-authorize and then it works again. but this is CUMBERSOME.

So I guess I need to file a bug, but...
1. it asks me for a package - how do you I know which package this is about...?
2. This is critical for me, it means that every morning when I come to work I have to do this (at sometimes more than once a day, for example - again after lunch...)

Thanks for the help!
