Thanks for your dmesg and acpidump. I will find some time looking into
them.

As for debugfs, every major distribution have it enabled [1] and so do
any sane downstream kernel. debugfs can only be accessed by the root
user by default. Did you try with the root user (e.g., `sudo -i')?

[1]: https://oracle.github.io/kconfigs/?config=UTS_RELEASE&config=DEBUG_FS

And since you are using a downstream kernel, could you provide a link
to its website or so? So that I can check if it's the root cause
(though unlikely).
