Hi,
After upgrading to -test5, my bt878 card ceased to function properly. My
kernel is tainted with the nvidia kernel module but I know for a fact that
bttv worked just fine not too long ago and I have not upgraded my nvidia
drivers since.
I have the following message in my dmesg:

Can you reproduce it without the nvidia module and produce a call
trace that doesn't include nvidia symbols?

Yes, and then try bttv patches from http://bytesex.org/bttv/
2.6.0's bttv driver is misbehaving in my setup for ages... Try bytesex's
patches and report back, please.

It seems to work even with the nvidia module loaded, but once I start X, it
stops working. I thought that perhaps the patch to the nvidia kernel module
for -test5 was broken, so I used my older 2.6 nvidia kernel module source
and replaced the call to kdev_val() with MINOR() but that still did not fix
the problem. I can cat /dev/video0 before starting X, but afterwards it
says "Device or resouce busy", even after I kill X.

I tried this set of patches and it didn't do anything for me either.
So am I pretty much on my own with this problem? Does anyone use a Bt878 card
with an nvidia card under 2.6? It's strange that it used to work just fine,
but after upgrading it stopped working. I might try downgrading later to
-test4, but it would be unfortunate to have to run an earlier kernel without
the VIA8237SATA chipset merged in =\
I read somewhere that Nvidia cards do not support the overlay extension, but
I had xawtv working just fine if I disabled Xv, and it worked even better if
I used grabdisplay.

Hi,
I'd also like to mention that the FM radio component still seems to work fine
and that I get a strange error whenever I attempt to access /dev/video0:
(along with the Device or resource busy error)
tuner: TV freq (268435455.93) out of range (44-958)

I have these:
# lspci|grep Brook
00:09.0 Multimedia video controller: Brooktree Corporation Bt878 Video
Capture (rev 11)
00:09.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture
(rev 11)
And this card (hauppagge wintv) works fine with 2.4 but doesn't work (at
least for long...) in vanilla 2.6.0-test1 -> test3. I'll try a newer
kernel shortly :-)
I also have a nvidia card but I don't have any nvidia drivers installed.
One more note: in my setup I must use "NoMTRR":
Section "Screen"
Identifier "Default Screen"
Device "nVidia Corporation [NV15]"
Monitor "Generic Monitor"
Option "NoMTRR"
... etc...
Or I'll get screen corruption sooner or later.
Good luck,
Nuno Silva
