## Копал долго. В итоге заставил систему проверить файловую систему при загрузке через создание файла /forcefsck После перезагрузки заработали RS485 подключения. Но с девайсами все та же беда - нет связи между интерфейсом и устройствами. Не работает свет. Копаю дальше. Связь восстановилась с модулями справа после физического передергивания питания контроллера!
