Kernel 3.13.1 – Better NVIDIA Patch, but Still Problems..

Installed kernel 3.13.1 on my main system, and found a better version of the NVIDIA patch for driver 331.38 here: http://cvs.rpmfusion.org/viewvc/rpms/nvidia-kmod/devel/nvidia_3.13_kernel.patch?revision=1.3&root=nonfree&view=markup

Video playback – especially on kaffeine – is better, but I am still getting problems with uvcvideo and usb audio etc:

.......
[  841.265226] uvcvideo: Found UVC 1.00 device VF0700 Live! Cam Chat HD (041e:4088)
[  841.266633] input: VF0700 Live! Cam Chat HD as /devices/pci0000:00/0000:00:1a.7/usb9/9-2/9-2.7/9-2.7:1.0/input/input11

.  etc....

And the NVIDIA driver segfaults:

(EE) Backtrace:

(EE)
Fatal server error:

I installed Kernel 3.13.1 on a non-NVIDIA test system (with the standard kernel.org drivers) and there appeared to be no problems:

[   34.550537] uvcvideo: Found UVC 1.00 device VF0700 Live! Cam Chat HD (041e:4088)
[   34.551973] input: VF0700 Live! Cam Chat HD as /devices/pci0000:00/0000:00:1d.7/usb8/8-1/8-1:1.0/input/input17

[   35.246033] usbcore: registered new interface driver snd-usb-audio

So..  I am staying with Kernel 3.12.9 on my main system, for the time being…    Hopefully NVIDIA will release a driver with full 3.13 support soon…
