Greetings,
I'm pulling my hair out :-) trying to figure out where to look next so i was hoping
someone might recognize this and be able to point me in the right direction.
I have a Pinnacle PC-TV Pro (card=52, tuner=21), a Creative SBLive! sound card (audio
from the PC-TV Pro fed into the SBLive via the little cable), and tulip-based ethernet
card and brain-dead SiS-based PCI VGA card for what that's worth.
I got a fresh 2.4.18 kernel, patched it to 2.4.19-rc3, applied the
v4l2-api-2.4.19-rc3.diff patch, installed videodevX-20020330 from thedirks.com, and
finally installed bttv-0.8.43. Amazingly, everything seemed to go just fine,
including insmod-ing video-buf and bttv (card=52 tuner=21). However, when I try to do
something like:
v4lctl setstation 19
I get a stack dump in /var/log/messages:

and now I really don't have a clue where to go next. (BTW, this v4lctl is from the
xawtv 3.76 build.) Can anyone please point me in the right direction, considering
that I am not by any means a "kernel hacker"? Thanks!
