OK, I managed to bisect this issue being introduced by http://linuxtv.org/hg/v4l-dvb/rev/7276a5854219 which puts the tuner into sleep mode when no used.
At first glance, it looked like I would be able to use the no_poweroff=1 tuner-xc2028 kernel module parameter to workaround this issue, but the issue still occurred due to i2c bus fiddling in dvb_frontend.c. I was able to find another workaround with the standard ubuntu packages without requiring a recompile. Just add the following line to /etc/modprobe.d/options options dvb-core dvb_powerdown_on_sleep=0 I'll follow up with the maintainers to get this fixed upstream. -- regression: support for dvico dual digital 4 card https://bugs.launchpad.net/bugs/459523 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
