Comment 1 Sergey Vlasov 2009-05-07 21:52:14 MSD

А как удалось повесить ошибку на пакет kernel-modules-3c90x-std-up, который уже много лет не существует?  На самом деле проблемный модуль находится в пакете kernel-modules-v4l-std-def.

Действительно, сломано (и не только saa7134-alsa - ещё несколько драйверов используют snd_card_create()):

Надо исправлять:

На него остались закрытые ошибки, так что компонент всё ещё есть. To be fixed Real Soon(tm).
