>From latest HEAD on a Dell Precision 7550 laptop: https://gist.github.com/lattera/a0803f31f58bcf8ead51ac1ebbc447e2 The last working boot environment was 14 Aug 2020. If I get some time to bisect commits, I'll try to figure out the culprit. Thanks, Shawn Webb (Sorry for the brevity. Only partially working system due to above breakage.)
