Bug with video cards.

[<paul.van-de-velde@home.nl>]

Dear reader,

I would like to report a bug with video cards of which I guess it is located in the kernel (but not certain). It is only happening in FC6 not in Suse 10.2).
However I like FC6 better as Suse 10.2 and I would like to see this bug fixed.

I tried to install a bluecherry PV149 video capture card and after a lot of investigations it turns out the framebuffer address is wrongly set.

Also other people with other HW are experiencing the same kind of issues.

Here are some logs:

No it is not the HW. I have XAWTV working now. The solution was found under:
http://www.mail-archive.com/mjpeg-users@lists.sourceforge.net/msg07044.html

It seems to be a FC6 issue. You have to find the framebuffer address under /dev/log/Xorg.0.log. Do a search for framebuffer and you will find the address.

The address is 0xF000 0000. One can set it n XAWTV with the command:
v4l-conf -a 0xF0000000. 

Thanks for a solution.

Cheers,

Paul
