[mythtv-users] ivtv-fb freezes my Mythtv system after loading - please help

Sat Dec 4 15:40:53 UTC 2004

(Sorry if this message pops up twice in the list but I don't see my 
message posted yesterday.)

I'm having lots of troubles getting my X on TV out of the Hauppage 350 
to work. After loading the ivtv-fb the system freezes. 

That is: 

- When I boot the system without X and load the ivtv-fb module the 
console freezes. I get some text output of the ivtv driver on the screen. 
- When I boot the system with X, I can load the ivtv-fb driver but it 
doesn't work. (no X on the tv-out) and when I try to logout X, shutdown, 
reboot etc. the system freezes after it has closed X. 

ivtv does work (I think) because I can capture video on the Hauppauge 
350. I'm also able to play it on the tv screen with: 
dd if=test.mpg of=/dev/video16 bs=64k 
but the ivtv-fb drives me crazy 

I'm using the ivtv drivers installed with apt-get (instructions on 
Jarod's page)

Can some-one please help? What can I try? ivtv 0.2?

Here is some aditional info of the system status: 
=================================== 
OS: Fedora Core 2 Kernel 2.6.9-1.6_FC2 
ivtv 0.1.10-48.3_pre2_ck100zz 

I have tried add video=vc:0-0 like suggested in the ivtv-fb.c 
grub.conf: 
title Fedora Core (2.6.9-1.6_FC2) Video 
root (hd0,0) 
kernel /vmlinuz-2.6.9-1.6_FC2 ro root=LABEL=/ rhgb quiet video=vc:0-0 
initrd /initrd-2.6.9-1.6_FC2.img 
but nothing changes.

My modprobe.conf looks like this: 
alias snd-card-0 snd-atiixp 
alias char-major-61 lirc_i2c 
install snd-atiixp /sbin/modprobe --ignore-install snd-atiixp && 
/usr/sbin/alsactl restore >/dev/null 2>&1 || : 
remove snd-atiixp { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; 
/sbin/modprobe -r --ignore-remove snd-atiixp 
alias usb-controller ehci-hcd 
alias usb-controller1 ohci-hcd 
alias eth0 3c59x 
# ivtv modules setup 
alias char-major-81 videodev 
alias char-major-81-0 ivtv 
#install ivtv /sbin/modprobe --ignore-install ivtv; /sbin/modprobe ivtv-fb 
install lirc_i2c /sbin/modprobe ivtv; /sbin/modprobe --ignore-install 
lirc_i2c 

When I remove the '#' before the "install ivtv /sbin/modprobe 
--ignore-install ivtv; /sbin/modprobe ivtv-fb" the system freezes after 
booting and loading ivtv-fb 

Messages after modprobe command:

After this I exit the root terminal in X and shutdown the system with te 
menu:

Nothing strange I guess?
