Created attachment 357798 [details] emerge --info I use gentoo as a receiver. I used =sys-kernel/gentoo-sources-3.8.13 with xbmc-12.2 and =media-tv/tvheadend-3.2 all works fine. Today i upgraded to =sys-kernel/gentoo-sources-3.10.7 and tvheadend cant find the hardware (cx23885). It seems to load the firmware. =media-tv/w_scan-20130331 can scan tv sender and is ok, but tvheadend dont do it. All i can say is, if i boot the old 3.8.13 kernel, the card works.
I'm trying to bisect linux-stable.git and determine the commit id, which introduced the bug. This can take some time.
Created attachment 357852 [details] bisect information for bug
The offended commit is contained in v3.10.7 but not in v3.8.13. c1965eae65f0db2eee574f72aab4e8b34ecf8f9c is the first bad commit commit c1965eae65f0db2eee574f72aab4e8b34ecf8f9c Author: Konstantin Dimitrov <kosio.dimitrov@gmail.com> Date: Sun Dec 23 19:25:09 2012 -0300 Bye Georg
Seems to talk about using an external (out of kernel?) tuner driver in the commit log message; hmm, you could try to contact the author for more information.
No its in linux-stable.git
git remote -vv origin git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git (fetch) origin git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git (push)
Yes, that I know; please read my previous comment again and read the commit log message at http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=c1965eae65f0db2eee574f72aab4e8b34ecf8f9c
Hi Tom, i wrote Konstantin an email and pointed him to that bug report. If i dont get an answer i'll mail to the linux-tv ML. Bye Georg
I digged a little in the code an saw that the ts2020 is now a own module. This module gets loaded with 3.10.7. [ 11.096303] ts2020_attach: Find tuner TS2020!

Got no answer from Konstantin, so i wrote to the ML. Lets see what happens ;)
Got no answer from the ML, so i filled an bugreport on kernel.org https://bugzilla.kernel.org/show_bug.cgi?id=61131
