Hi there, I've been having a hell of a time with my TV card and new motherboard. It's a Soyo k7ada with a 1ghz Athlon & DDR ram. I have three video cards at my disposal, and the only one that works is the PCI one. The other two AGP cards cause bttv to lock up. The TV card is a hauppauge new (bt878 -- see dmesg below), and it works fine with any video card in my PII-400mhz system. I've tried compiling the kernel with & without agpgart support, and also with & without matroxfb (my current card is a Matrox G200 8MB), and all combinations seem to lead to the same crashes. The crashes occur whether I use xawtv or fbtv. (I've also tried bttv 8.x... it seems to work better (except for fbtv which doesn't work) but I still lock up).. I'v also tried varying the resolution depth. Right now I'm at 24bpp, but 16bpp caused the same problems. So I'm convinced it's some sort of AGP incompatibility. Basically what happens is the screen will freeze for a little bit, and then eventually the video will freeze for good and by then the kernel has frozen the system. The audio keeps going. With fbtv, the first time I start it up, the display overlay doesn't seem to get initialized, and all I get is a horizontal line. The next time I start it up, it'll be fine, but it will eventually freeze up like xawtv. I've included the relavent /var/log/messages entries.. the first section is what usually shows up in the log after a crash. The last section doesn't show up much, but it may be relavent. And sometimes, there is also an oops log from the X process, but that doesn't happen very much... Let me know if I can do any debugging for you, or try out the latest 2.4.13pre. I'll be glad to help, as I love my new computer but miss my TV!! Thanks, Mike ========== lspci: 00:00.0 Host bridge: Acer Laboratories Inc.
