Hi
Just an uppdate on this problem I have now tested kernel version
2.4.23-pre5 plus (patch-2.4.22-bk30-bk3) that includes the following
changes:
v4l i2c modules update
o bttv driver update
o bttv documentation update
o Tuner update
o videodev update
And the result is that 2.4.23-pre5 works fine but 2.4.23-pre5 plus the
patch patch-2.4.22-bk30-bk3 hangs the system when one tries to use the
video device with Gnomemeeting.
So the following patch somehow caused this lockup problem with
gnomemeeting and my bttv card:

Hello
It seems that I have encountered a bttv problem that is 100%
repeatable.
What happens is that the system freezes and the keyboard
lights are flashing if I press the preview button in Gnomemeeting or
if I start to send video from the bttv card over the network.
My system:
- Fedora core 1
- gnomemeeting-0.98.5-1
- pwlib-1.5.0-2 (used for low level access bye gnomemeeting)
- kernel 2.4.23-pre9
- gcc version 3.3.2
What I have tried is that with the original kernel and up to
2.4.23-pre5 so does Gnomemeeting work but after 2.4.23-pre6
so dose the system freeze when gnomemeeting is accessing the video device,
xawtv works without any problems.
So it seems that these driver changes below causes the problem for me:
Gerd Knorr:
o v4l i2c modules update
o bttv driver update
o bttv documentation update
o Tuner update
o videodev update
When the system is oopsing or freezing so do I get this in the log:

can test.
