Eu tenho um servidor Ubuntu 14.04.1 com um servidor backend MythTV e um adaptador Digital Devices DVB. O servidor tem funcionado bem, mas se eu atualizar o kernel de 3.13.0-34 para 3.13.0-35 / 3.13.0-36 meu adaptador DVB não será mais detectado corretamente. Sob o kernel 3.13.0-34 eu tenho estes dois "catálogos" em / dev:
/dev/dvb/adapter0/frontend0
/dev/dvb/adapter1/frontend0
Em 3.13.0-35 e 3.13.0-36 todo o catálogo dvb está faltando.
O lspci me fornece o mesmo resultado em todas as três versões do kernel:
02:00.0 Multimedia controller: Digital Devices GmbH Octopus DVB Adapter
Under 3.13.0-34 Eu sou perfeitamente capaz de gravar qualquer coisa que eu quero, mas quando eu inicializo com 3.13.0-35 ou 3.13.0-36 meu mythbackend.log mostra isso:

Não me lembro de ter visto erros quando atualizei para o 3.13.0-35 ou 3.13.0-36. Alguém aqui pode me ajudar a conseguir meu adaptador DVB funcionando novamente sob 3.13.0-35 ou 3.13.0-36?
Atualmente estou inicializando o servidor usando o kernel 3.13.0-34, mas eu preferiria usar o kernel mais recente disponível a qualquer momento.
Quando instalei o servidor, usei o dddvb-dkms para obter os drivers para o adaptador DVB. Poderia ser um erro no dddvb-dkms 0.9.14.1yavdr1 que está causando os problemas sob os dois kernels mais recentes?
