My motherboard is an Infinity NF ULTRAII-M2.  According to the
manufacturer's website, the chipset is an NVIDIA nForce4 Ultra.

Basically, I'm going from a number of other posts to the ivtv-users' list
complaining of DMA errors, with the recommendation being to upgrade the
driver to a non-faulty version.

Sigh... so I guess my choices are to live with the lockups, or to learn how
to build and upgrade a kernel from scratch, separately from my Ubuntu and
Mythtv releases?  Search this list for "kernel upgrade", and the result is a
wasteland strewn with driver, application, and OS nightmares...

Is there a way to re-create the Feisty kernel (2.6.20-16) with the only
change being the ivtv driver?
