A search revealed that a kernel automated test robot flagged a bug in that commit: https://lore.kernel.org/lkml/20200327074308.GY11705@shao2-debian/ which resulted in this discussion: https://lore.kernel.org/lkml/20200327175350.rw5gex6cwum3o...@linutronix.de/ about a race condition. The end result was this patch: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=62849a9612924a655c67cf6962920544aa5c20db However, I *think* that it is only about an erroneous warning message. With regard to the problematic commit that bisection revealed to you: https://lore.kernel.org/patchwork/patch/1050496/ Can you try with a very recent kernel package, and then revert just that commit (manually, in an otherwise stock kernel tree, using the -R option with patch) Does the problem go away? If so, it would certainly confirm there is an issue with that commit. And given the discussion among the developers about what is what, it seems it is very easy to make a mistake or oversight in that code. As to why it only happens to you, maybe a certain combination of config options is needed to trigger the problem.
