Hello
I just recently upgraded my motherboard to an MSI KT4 Ultra, after that my tv card ceases to work.
I have a TV Wonder VE (bttv) tv card.
Xawtv segfaults on scanning for channels and kwintv craps out.

However I do have Sound, just no picture.
Kwintv will open with a black screen but nothing else.

The correct modules are either built into the kernel or as modules like bttv.o and tuner.o.

I also reinstalled my whole system and I used the same kernel config, except I changed the sound modules for my sound card (for the new mobo).

Heres what happens when i modprobe the bttv module. (from the system logs)

-----------------------------------------------
It finds it, ie I don't need to add modprobe bttv card=64 etc, it finds it fine as usual. It just dosen't work.

Here is what kwintv says:

I also have DGA enabled in my XF86Config.
Anyone have any ideas?
Thanks.

well surely you're simply not tuning it in properly or something? there are obviously no error messages anywhere, so nothing to go on. have you tried xawtv as well? much nicer that kwintv...

As I said xawtv dosen't work. Using scantv segfaults, and using a old config dosen't work.

My mobo is also new as I stated, I checked kernel.org and I seen 2.4.21pre1 and checked the change log, AGP support for my machine (I have AGP 8x)
and other fixes.

Im going for some sort of conflict with the agp, my nvidia card and the tvtuner.

I popped the tv card in another slackbox I have with the same conf and it worked fine.

By the way
I like kwintv better, it picks up color with out needing to change anything.
In xawtv I would need to mess with the hue etc.

Hmmm interesting problem. I haven't got a solution for you but it seems kinda related to my problems.
I've got an MSI KT4 Ultra motherboard and I've been trying to get my tv-tuner card to work on it. Not really much luck so far. The card I have is a kind of unknown card though but it does have the bttv chip in it. The chip says b878a on it. It says it's from Tevion and it's just a cheap card I got to play around with. I'm pretty sure it detects the tuner properly because with scantv it does detect all the channel names properly at the right frequencies. But I just haven't managed to get any picture yet. I haven't really tried the sound yet since I wanted to see something first before I tried the sound.
I've tried all the different card types and there are several of them which I get no errors with, except that my screen stays black.

I don't know how far the AGP settings would affect the tv tuner card though. But I do have problems with the agpgart driver supplied with the kernel (2.4.20). It detects an unknown chipset, I can force it to load but then it doesn't work that well either. So right now I've set it to use the stuff from the NVidia driver which seems to be working pretty good. Still haven't tried any of those 3d games or anything like that on it yet.

But to get back to the tv card. Right now I've kinda went through all my options of different things to try, besides hacking into the bttv driver which I don't have a lot of time to get into right now. I know the card physically works, because I tried it in a windows machine (apart from the fact that it spontaneously reboots the computer when it's tuning channels). Maybe I should get linux running on the windows machine and see if it works there. That would rule out the problems with the motherboard.

It seems to be the motherboard, its just too new.
I'v been googiling all night and have found some interesting things:

It seems to be the AGP.


The mobo is also brand spanking new, and I *was* having the DMA problems everyone else was.
I patched my kernel to 2.4.21pre1
I get this now:

I use hdparm to turn on DMA manually in my rc.local and it seems to work fine

So far here are the problems im having
#1 Somthing is bothering my other devices like my tv card
#2 Minor DMA problem
#3 Can't play games.
Other than that everything works, I can play mp3's, general web browsing, email, etc.

Im hoping someone writes a patch for my board soon,I run straight Slackware Linux, its not a choice for me to reboot into windows like most people and continue working.

Anyone have any links or information about my board and when is it going to be supported in linux, who's working on it, when will a fix be released, etc?

Thanks

I had some time to play around with my tv-card and actually managed to get it working. This might be specific to the card I have but I had to add the option pll=1 for the bttv option. I got it working with xawtv and had to set capture to grabdisplay to actually get picture instead of a black screen. I haven't really looked into what that setting does yet. Still get a bit of faded colours on some channels though.
I have kernel 2.4.20 and added the patches for v4l2 and the 0.9.3 bttv driver.

I haven't added any patches for DMA support but my IDE controller is properly detected and does set both harddrives and cd's in DMA mode. All I had to do was enable the option in the kernel which forces it to enable dma.

I was reading through those two links you gave but I'm only having problems with the agpgart driver. Gotten around that so far by using the AGP support in the nvidia drivers instead. No problems with sound or DMA.

This is the output of hdparm -t so I assume it's working well:
/dev/hdc: Timing buffered disk reads: 64 MB in 1.28 seconds = 50.00 MB/sec

Well I'd say keep trying I'm sure you'll get it working.
