Mavros: serial0: terima: Akhir file

Detail masalah

Hai.
Terkadang saya mendapatkan pesan "serial0: accept: End of file" saat menjalankan mavros (tidak ada yang terhubung ke autopilot), meskipun saya dapat terhubung secara normal melalui mavproxy, APM Planner, dan QGroundControl.
Restart autopilot tidak membantu, hanya restart PC.
