bttv grabbing problems with recent kernels

[Andriy Rysin]

Hi,

I've posted this to video4linux-list@xxxxxxxxxx and got one confirmation 
of the problem and it seems like it's a kernel issue so I dared to post 
here. Please CC me on reply.

I've got some problems grabbing with bttv on recent kernels. If anybody
can confirm the problem or even help with this issue I would really
appreciate that.

The comandline is this:
streamer -c /dev/video0 -s NTSC -s 640x480 -f jpeg -o /tmp/foo00000.jpeg
-t 0:120 -r 30

I was using 2.4.20-6 from older rawhide and everything worked perfect -
every frame is grabbed. streamer is from xawtv 3.83.

On kernel-2.4.22-20.1.2024.2.36.nptl (wether UP or SMP) from recent
rawhide streamer misses about every 10th frame

On kernel 2.6.0-0.test5.1.34 it does it for every second frame, the
output is below.

This behavior was confirmed on 2.6.0-test3 with saa7134 driver compared 
to ok with 2.4.20.

I must say that with kernel 2.4.20-6 I was doing up to 80 frames per
second from 4 cards on same server so this is not CPU/chipset/grabber 
card/PCI throuput issue. My dmesg and lspci are attached.

bttv used with kernel 2.4.20 is 0.7.96 (and 0.7.97), bttv for 2.4.22 -
from kernel rpm (0.7.107), bttv for 2.6.0 - from kernel rpm (0.9.11)

Thanks in advance,
Andriy
