Tested out the merged version of my Pinnacle 801e support (it went in to the v4l-dvb mainline this morning). It turns out a regression got introduced after my commit which causes the driver to panic the kernel.
I have submitted a patch to fix the issue. In the meantime, stick with the patch I provided in the earlier post and *don't* update to the latest v4l-dvb.
Thanks,
Devin
