Bug 248288 – sys-kernel/gentoo-sources-2.6.26-r3 upgrade -> tv card doesn't work

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Atanas Kamburov 2008-11-23 12:56:13 UTC]

After kernel update from 2.6.25-gentoo-r7 to 2.6.26-gentoo-r3  ( used make oldconfig ), i cannot watch any more TV :(. Got a Hauppauge Wintv PCI card and I watch TV through tvtime. /dev/video0 is still there, but tvtime says "no signal". If I start the PC using the old kernel without changing anything else, I can watch TV without problems. The same options under Device drivers -> Multimedia are selected in the kernel menuconfig in both cases (old and new kernel).

Reproducible: Always

Steps to Reproduce:
1.update kernel to gentoo-sources-2.6.26-r3
2.start tvtime
3.

Actual Results:  
blue screen; tvtime sais "no signal" for every available channel.

Expected Results:  
watch some TV

Problem fixed: looks like 'make oldconfig' was not enough. I have disabled a couble of options related to v4l1 compatibility (that were enabled in the older kernel btw) and now Mr Obama is waving from the screen...

[Comment 2 Atanas Kamburov 2008-11-23 13:56:23 UTC]

hm, disabling the v4l1 related stuff caused skype to crash when starting the video. so i turned those options back on, and finally realized that the fix came actually from compiling the tuner driver as a module (it was built-in in the former kernel).

so, if anyone has a similar problem, try building the tuner driver as a module and do NOT disable the v4l1 options if you are using skype with a camera.
