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 Fedora kernel and up to
2.4.23-pre5 so does Gnomemeeting work ok, but after 2.4.23-pre7
so dose the system freeze when gnomemeeting is accessing the video device, xawtv works without any problems.

So it seems that it might be these bttv driver changes below that causes the problem for me:

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 system log:

bttv0: irq: OCERR risc_count=2fd87020
bttv0: irq: SCERR risc_count=2fd87020
bttv0: irq: OCERR risc_count=2fd87020
bttv0: irq: SCERR risc_count=2fd87020
bttv0: irq: SCERR risc_count=2fd87020
bttv0: aiee: error loops
bttv0: resetting chip
bttv0: PLL: 28636363 => 35468950 .. ok

Or like this:

bttv0: irq: OCERR risc_count=2fd87020
bttv0: irq: SCERR risc_count=2fd87020
bttv0: irq: SCERR risc_count=2fd87020
bttv0: irq: OCERR risc_count=2fd87020
bttv0: irq: SCERR risc_count=2fd87020
bttv0: aiee: error loops
bttv0: irq: SCERR risc_count=2fd6c014
bttv0: aiee: error loops
bttv0: resetting chip
bttv0: PLL: 28636363 => 35468950 .. ok

Some information about my system, I have compiled everything into the
kernel:
