### Firmware Version

2.7.15

### Description

I am trying to setup Meshtastic on a RPI Zero 2W using the Linux native firmware and `meshtasticd`. I have a MeshAdv Pi Hat equivalent using the same pinout and the E22-900M30S.

I've been able to reproduce this issue on both the `alpha` and `beta` releases of `meshtasticd`, currently using `alpha`.

Below is my `config.yaml` output from `meshtasticd`:
```yaml
Lora:
  Module: sx1262

General:
  ConfigDirectory: /etc/meshtasticd/config.d/
  AvailableDirectory: /etc/meshtasticd/available.d/
  MaxMessageQueue: 100
  MaxNodes: 200
```

This problem happens right after trying to transmit a packet, e.g. when running the following CLI command: `meshtastic --host 192.168.8.199 --sendtext "This is a longer test message for radio verification"`. After running and getting the `[RadioIf] Can not send yet, busyRx` warning, the API interface stops working until a `meshtasticd` restart. While it is stuck `meshtasticd` uses 100% of one CPU core. I have tried resetting the transceiver through the GPIO reset pin, as well as power cycling the entire system.

I haven't been able to compile `meshtasticd` from source on the pi as `pio run` exits mid-compilation with no warning/error. I'm using the `trixie` image on the pi with the Lite install of Raspbian.

I can provide any other needed logs or tests, please help me resolve this issue.
I have 2 other nodes on esp32s3 and those have been working flawlessly. Checking with an RTL-SDR the pi has never managed to send any packets, and this error persists even when absolutely no LoRa packets have been on air / received since a power up (there are 0 nodes in my area).
