Oh, wth.... That didn't cross my mind. I had 1.16, which was latest last time I
checked (end of June), now there is 1.22 and 1.24.

Upgraded to 1.24, suddenly there are issues with drm-kmod, booted single-user,
disabled it, system boots fine, ran my "WireGuard" panic-maker and... it's not
working anymore (aka no panic).

These are the release notes, does any of that sound like it could have fixed
the issue?

This sounds super suspicious to me but I can't really parse the meaning out of
this English:

- [Important] Modify WMI AmdVt item can't modify and remove unuse item


I'll reactivate WireGuard on my day-to-day and keep an eye on things, if in a
few days the panic doesn't happen again, I'll close this bug.
