I should have clarified this, my apologies.
I am running the latest V4L from the official V4L HG repository. I have
bluntly built and installed it on top of the Ubuntu kernel, replacing
V4L entirely.

Other users with same card and kernel has reported no issues with the
same configuration. And the card works for a while...

I realize this is not optimal, though.

Don't know why I didn't think of that. I'll see if I can do similar for
Ubuntu to signal the need.

Interesting. I will see if I can get it working similarly on the Ubuntu
.31 kernel.
