If you are on main, you can simply update.  If you are on stable/13
you want or wait until I'll MFC:

git cherry-pick -x 170acccf1e191ae28571845ad6f0b5a2fbf0effc

And many thanks to JR for his work on this!


While this seems to have helped, I can still crash on my 8265 but I
have probably learnt to twist knobs to do that in the last weeks with
AX200.

I'll be very happy to hear if this helps you (and others on more
modern chipsets).

Later,
Bjoern
