Comment 23 for bug 1696325

Hi guys, I have indirect comment, but related to thuderbold support. I have Dell xps 13 and by running on 4.12.12 kernel I get same messages on Dell DA200 UCB-C adapter (provides HDMI and Ethernet and VGA and USB). In didn't get it working yet, but just testing it with latest available kernel on Gentoo system =4.15.7 (release 1).

I found in my case information that it might help if I upgrade the thunderbolt firmware in the laptop, which dell made open source: https://github.com/dell/thunderbolt-nvm-linux

Not sure if HP provides you with Thunderbolt firmware update for Linux (although in case of Dell the files are extractable from Windows CAB files, but I am studying it at the moment)
