Добого времени суток.
Ноут с gentoo на борту используется для записи видео с аналогового источника (захват через тюнер saa7134), звук - со встроенного микрофона.
Скрипт, который запускает захват видео:

После очередного выхода из спящего режима видеозахват работать перестал.
Сам тюнер работает - «ffplay -i /dev/video0» картинку показывает. Скипт ругается на 24 строку - gst-launch-1.0 Bus error.
