The error came back after I updated my router again. Here are the
oops'es with KALLMSYS enabled:

This is with the same image as last time (commit
f6e6eadc99c6274207f8f2ebc739063549959a1f) and configuration (radios
used as clients). I see that mt76 has been updated during the weekend
so I will go ahead and compile a new image with the latest updates.
BR,
Kristian
