I just build a ~2025.04-rc5 (i.e. 'master') version and tried it on my
Q64-B and the problem is still there.
Furthermore, there have now been several ppl on #quartz64 IRC channel
(on Pine64 IRC network) who have confirmed both the problem and the
'solution'/workaround. Hopefully they'll also report here themselves.

I didn't try it this time; I just dd-ed my patched 2024.07 version and
then everything worked again.

It would be nice to get this fixed. I don't know how to fix it myself,
but I'm happy to test a potential patch for it.

Cheers,
