Ещё один момент, у вас драйвер npreal2.ko грузится из каталога с ядром #!/usr/bin/bash modprobe npreal2 ttymajor=33 calloutmajor=38 verbose=0 if [ -e /usr/lib/npreal2/driver/state.start ]; then /usr/lib/npreal2/driver/mxloadsvr fi При обновлении ядра (что в убунте происходит довольно часто), приходится либо снова запускать скрипт установки, либо руками копировать файл драйвера. Я просто поправил скрипт запуска и перенёс модуль в каталог с драйвером. После этого проблема снялась. #!/bin/bash /sbin/insmod /usr/lib/npreal2/driver/npreal2.ko ttymajor=33 calloutmajor=38 verbose=0 if [ -e /usr/lib/npreal2/driver/state.start ]; then /usr/lib/npreal2/driver/mxloadsvr fi

Заработало. Спасибо!

На версии ядра 5.15.0-43 не собираются драйверы. Будут под новую версию ядра?
