Comment 1 George 2014-10-29 01:02:53 UTC

I can confirm that the patch below allows the DVICO USB DVB-T dongle to tune DVB broadcasts OK.  I have recompiled and istalled a recent fedora kernel with a patch based on the documented change.


https://patchwork.linuxtv.org/patch/24567/

This issue is also seen in RHEL7.

Thanks for the pointer.  That went into the upstream 3.17 kernel as commit eb9da073bd002f2968c84129a5c49625911a3199.  We'll look at backporting it soon.

You will need to file a bug against the RHEL product if you want to see it fixed there.  The Fedora kernel maintainers do not work on RHEL.
