[mythtv-users] Kernel Crash when starting up in au828-video.c line 895

[Rollerfeet, Johnny]

I saw this as a previous topic in early April, but I didn't see a
resolution. I am having problems adding a USB Hauppage 950Q to my
Mythbuntu system. Oddly, it was working fine in a previous box (with a
slower Intel CPU), but when I started with a fresh install my
new(-to-me) AMD system I can't get MythTV to load when the USB tuner
is connected.

I'm going to continue building out the system, but someone please save
me from telling my wife I'm going to buy new tuners.
