Здравствуйте!Собираю модуль для MOXA CP-168U V2.
Если кратко, версия ядра 2.6.39-400.298.3.el6uek.x86_64, а модуль собирается под 2.6.32-696.23.1.el6.x86_64. Почему и как это исправить?
# uname -srv
Linux 2.6.39-400.298.3.el6uek.x86_64 #1 SMP Mon Feb 26 09:51:27 PST 2018
# lspci | grep -i Moxa
0a:01.0 Serial controller: Moxa Technologies Co Ltd CP-168U V2 Smart Serial Board (8-port RS-232)
make и make install проходит без ошибок.
Пытаюсь загрузить модуль:

Откуда берётся информация о старом ядре? Где что поправить, чтобы собрать модуль под текущую версию ядра?
