Comment 35 for bug 229879

Robert Lowery's suggested work around addresses the issue in Mythbuntu 8.04
(Hardy). I have done the update suggested:

adding

options dvb-core dvb_powerdown_on_sleep=0

to /etc/modprobe.d/options.conf
I have tested by doing a warm reboot, and also by stopping and restarting
myth-backend. Both of these techniques would consistently reproduce the bug
previously. Now I can do both operations multiple times and the bug is not
reproduced. Looks like this workaround works for this bug as well, at least
in Hardy. I will try in Karmic later this week.

I have run Karmic, prior to testing this workaround, and the problem still
existed. In addition, I still needed to put the xc3208-*v27*.fw firmware
file in /lib/firmware.

Many thanks to Robert Lowery for analysing this problem and suggesting the
workaround.
