I reverted 4df96ba6676034 from v6.10.2 from the stable/linux git, resolving the conflict by removing everything that git marked as from the current branch and kept everything marked as from before the branch to merge. That resulted in a patch that is fixing the problem on my machine. Since I don't understand what the code is actually doing it might break things on other machines.
