I had to replace an apparently dead tv tuner card, and was hoping to get my
first taste of HDTV, as there are at least a couple of HD broadcast channels
here, so I picked up a Kworld ATSC120 from Newegg a few days ago.
I can't tell which mailing list this should go to since there seems to be at
least two lists covering this topic, so please forgive the crosspost if it's
in error.
After reading through both of the mailing lists that this message is destined
for (video4linux-list and linux-dvb) , and consulting the video4linux wiki as
well as a few other sources, it looks to me like this card *should* work
using the driver intended for the Geniatech HDTV Thriller X8000A, as one
appears to be a clone of the other.
However, I've hit a solid brick wall :(
I've downloaded and installed the 2.6.24.2 kernel, and fetched the most recent
snapshot of Mauro Carvalho Chehab's repository (which is what seems to be the
thing I need) from http://linuxtv.org/hg/~mchehab/cx88-xc2028/
I have compiled and installed the drivers and used the following to start
them:
-
modprobe tuner debug=1
modprobe cx88xx card=63 core_debug=1 i2c_debug=1 audio_debug=1
modprobe cx8800 irq_debug=1 video_debug=1
modprobe cx88_alsa
-
This results in the following modules being loaded:

(Also, nvidia, ali_agp, and agpgart are present)
If I also try to load cx8802 right after cx8800, it destablizes my system,
locks most of the other modules in (they can no longer be unloaded), and
throws a kernel BUG:
