Public bug reported: I've filed with ubuntu-bug so additional logging should be available.
Starting with 19.10 there has been a regression in my CalDigit thunderbolt 3 dock. With Bionic and Disco the dock has been stable across two laptops. After upgrading to Eaon and running 5.3.0-18-generic I'm getting periodic (every few minutes) resets of the dock. This presents as a loss of ethernet, microphone, audio, and video all of which are provided by the dock. Dmesg during the event: https://pastebin.canonical.com/p/VyrT4PDXW7/ I haven't changed the firmware on my bios or dock just the eaon upgrade. If there's more data I can provide please let me know.
