[Bug 459523] Re: regression: support for dvico dual digital 4 card

[Robert Lowery]

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.
