fixed it by flashing my previous Coreboot BIOS
Great job - well done!
Should I send my .config file so that you can tell if any of the config settings or combinations of them that I chose wouldn't work on my specific model of ThinkPad?
You can send the config but don't expect that someone else will analyze your problem.
Ideally, please instead investigate this yourself and share your findings (also along the way if you like) - if you can arrive at a clear conclusion then there is at least some possibility that someone else improves the code in case that makes sense.
Kind regards
