I'm guessing that these are accessed by something else in the system,
without properly putting its own vote or something.  Similar to
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.6-rc5&id=12eced09cd301aa7b1868a67c50a651c2aacd363

If I get some time, I'll try to repro and hopefully identify what is
exactly going wrong.
