I've submitted bug https://bugzilla.kernel.org/show_bug.cgi?id=112861 cxusb last worked for me in debian's 3.16.0-0.bpo.4-amd64, failed in 4.3 and 4.4. Oops and then panic within a second of plugging in the usb cable (or at bootup). My other usb tuner is working flawlessly. https://bugzilla.redhat.com/show_bug.cgi?id=1175001 might be a similar bug, and I tried reverting the patch here (since George talks about a new oops in the same timeframe): https://bugzilla.redhat.com/show_bug.cgi?id=1154454 but with no luck. What should I do next?
