I have exactly the same problem happening occasionally from a cold boot with
a Twinhan DVB-T clone. A further cold boot is required to clear the problem
(a reboot doesn't seem to solve it).
System is running 2.6.10-1.770_FC3 on a Gigabyte 7VM400AM-RZ motherboard with
one Visionplus DVB-T (Twinhan clone) and one Avermedia AverTV DVB-T 771 card.
I haven't yet had any similar problems with the Avermedia card. Any ideas?
When it fails to find the frontend output is as follows:

When it works, the last few lines of the above become:

It has been suggested that this may have something to with interrupts. On my
system a lot seems to be loaded on interrupt 11:
