kernel 2.6.15-26 breaks video4linux apps

[Robert Crosbie]

Binary package hint: kernel-image-2.6.15-26-386-di

I noticed that when I upgraded from 2.6.15-25-k7 to 2.6.15-26-k7 applications like camorama, motion and xawtv all stopped working. Reverting to 2.6.15-25-k7 allowed them work again. ekinga is the only application I know of where the video still works with 2.6.15-26.

I'm using a bttv based capture card:

It seems this is only a problem with 2.6.15-26-k7 since I tried the 2.6.15-26-386 kernel and the video4linux applications work with that. I do have an AMD processor (Athlon 2700XP)

Thank your for your bug report. Do you still have this issue with the latest release of Ubuntu ?

[Robert Crosbie (swingincelt)]

Unfortunately I do not have a way to test this. I have moved on to
Feisty (the problem does not occur) and have upgraded the mobo and
processor on the system that this occurred on.

Cheers,
Rob.
