[ date ] [ thread ] [ subject ] [ author ] I have the latest mythtv (mythbackend version: fixes/0.25 [v0.25.2-8-g3256849]) on mythbuntu 12.04. I'm getting the following error in my mythbackend.log Jul 27 17:22:11 mythbox mythbackend[8561]: W CoreContext dvbchannel.cpp:227 (Open) DVBChan(11:/dev/dvb/adapter0/frontend0): Opening DVB frontend device failed.#012#011#011#011eno: Device or resource busy (16) Jul 27 17:22:12 mythbackend[8561]: last message repeated 19 times Jul 27 17:22:12 mythbox mythbackend[8561]: E CoreContext dvbchannel.cpp:232 (Open) DVBChan(11:/dev/dvb/adapter0/frontend0): Failed to open DVB frontend device due to fatal error or too many attempts.

The server has been working fine, but if I upgrade the kernel from 3.13.0-34 to 3.13.0-35/3.13.0-36 my DVB adapter is no longer detected properly. Under kernel 3.13.0-34 I have these two "catalogs" under /dev: /dev/dvb/adapter0/frontend0 /dev/dvb/adapter1/frontend0 Under 3.13.0-35 and 3.13.0-36 the entire dvb catalog is missing. lspci gives me the same result under all three kernel versions: 02:00.0 Multimedia controller: Digital Devices GmbH Octopus DVB Adapter Under 3.13.0-34 I'm perfectly capable of recording anything I want, but when I boot with 3.13.0-35 or 3.13.0-36 my mythbackend.log shows this: Sep 24 20:43:18 obelix mythbackend: mythbackend[1761]: W CoreContext recorders/dvbchannel.cpp:229 (Open) DVBChan[1](/dev/dvb/adapter0/frontend0): Opening DVB frontend device failed.#012#011#011#011eno: No such file or directory (2) Sep 24 20:43:18 obelix mythbackend: mythbackend[1761]: E CoreContext recorders/dvbchannel.cpp:234 (Open) DVBChan[1](/dev/dvb/adapter0/frontend0): Failed to open DVB
