I assume it is the same issue with the up/down/up/.. cycle. I can normally do it three times before it goes kaboom (and I have a reproducer for it). I have also tried to execute the bringup and teardown bits I easily can in an endless loop which doesn't provoke the firmware to crash. That seems to indicate that we may need more state than I can (currently) easily produce for the endless loop. I keep poking at selective bits as a background task every other day currently and I'll try to see what I can do over the holidays on this. > Let me know if I can provide any further info that is not already > captured in the hw-probe or the screenshots. I cannot help much with the installer bits. If you were to do this with a non-crashing WiFi chip/driver would you ant any other changes there? If so you should probably raise that separately.
