After years of using my tv card on linux now it doesn't work.

I only upgraded kernel to 2.6.27 from official repo, and now my tv card won't work.

My tv card is Prolink Pixelview PV-BT878P+
it use bttv module

my /etc/modprobe.conf

#
# /etc/modprobe.conf (for v2.6 kernels)

alias char-major-81     bttv
options bttv card=70
options bttv tuner=5

02:03.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
02:03.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)

Is there some solution?

Re: bttv card dont work after kernel upgrade

I have two computers with TV cards (BT848 and BT878) and never had to change anything (aside from hardcoding the card number for the 848 in modprobe.conf) for them to be recognized after recent kernel updates.
Show your dmesg.

Re: bttv card dont work after kernel upgrade

Hm, I don't see anything obvious.
Make sure your user is in the video group, and then play with modprobe options, e.g. let the kernel autodetect the card, and if that won't work, try different card= / tuner= options.

Re: bttv card dont work after kernel upgrade

Having the same problem here. Allready thought that the card had died.
All logs appear normal, card is recognized etc. But since 19 oct I have timeout messages in the kernel.log I haven't seen before, like:

kernel: bttv0: timeout: drop=45 irq=1656/5138402, risc=72fd8024, bits: HSYNC OFLOW FDSR

I guess it's related to the problem.
