hmmmm ok, there's definitely something wrong... I suspect there could be an issue with the IRQ processing, as this usually happen when the SubMAC is not informed about a TX...

thanks for this one!

FYI: LoRaWAN requires all LoRa transceivers to implement FSK. In practice, this means all LoRa devices are also IEEE 802.15.4g capable devices. Getting this one in gets it one step...

I think I finally found what's going on with the corrupted FPU registers on native (I'm printing the `ftag` before every function call): ``` Found trace frame 29, tracepoint 2...

hmmmm digging deeper into the topic, it seems the `context` arg of the signal handler stores the last valid FPU register state. In [this patch](https://lkml.org/lkml/2021/9/27/54) they set the FP regs...
