Yes, doing an 'rmmod ath9k'  (or whatever that module is called)
sounds like a good idea, it might trigger the same lockup.

In fact, that might be the reason Harald sees this - maybe Void Linux
tries to unload modules before rebooting, and other distros don't?

Unloading modules doesn't tend to get a lot of testing, it's a fairly
unusual operation (and not one that is guaranteed to be safe - yes we
do basic module refcounting, but it's very basic indeed, not full).
