> ifconfig up
Done
> thread start
Done
> # hang

Steps to reproduce:

1. build and flash the nrf52840 CLI device by following https://github.com/openthread/ot-nrf528xx/blob/main/src/nrf52840/README.md
2. start GDB debugging by following https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/using-gdb-with-nordic-devices
3. start thread on the CLI device with ifconfig up and thread start commands.
