Comment 8 for bug 375224

just so you know I was getting the exact same errors alot when I ran Feisty Fawn with Mythtv .20.2-fixes. I made sure DMA was enabled for all drives and I even had the following options in my /etc/modprobe.conf
options ivtv enc_mpg_buffers=16 enc_yuv_buffers=20 enc_pcm_buffers=640 debug=3
BUT I still got the errors.

I just did a fresh install of Hardy Heron ( i wanted an LTS release this time) and with DMA enabled and having the above mentioned options in /etc/modprobe.d/ivtv I don't receive that error any more. I don't recall doing anything else with my setup out of the default install.
