Reboot after entering the SIM PIN
If you enter the SIM PIN right after startup, the Nokia 8110 4G panics and reboots after a while. If you wait a few seconds before entering the PIN, everything works as expected. This could either be a bug in the modem firmware that remained unnoticed on KaiOS due to a slower startup time or a bug in Bananian (e.g., some daemons not waiting for a ready signal).
