cx8800 DMA timeouts

[Alexander Oltu <alexander@xxxxxxxxx>]

Hello,

We have setup with Hauppauge WinTV model 34504.
We using that card only for taking SVideo capture. After few hours of work
it sends the following messages and video capture is not working until
module cx8800 is reloaded.
Does anybody had such problem or has an idea? Searching via mailinglist and
google didnt helped. There was few problems but related wrong tuner.
