[mythtv-users] using remote during playback freezes machine

[Nick Owen]

Greetings.  I am seemingly very close to getting mythdora 4 running. I
was running FC4 fine for a very long time, but had to make a move for
the SD service.  SD is great.  Glad it worked out. Mythdora is also an
excellent solution.

I'm running a very old p700 (free :) with a FX5500 from Nvidia and a
Hauppaugge 250.  Kernel is 2.6.22.9-61.fc6.  I was having lots of
trouble with X.  I disabled ACPI (apci=off in grub.conf) and that
stopped the immediate lock ups (seems that acpi was using the same
interrupt as nvidia and ivtv?).  Then I couldn't watch recordings -
they went fuzzy, pink and blue.  I switched on XvMC and playback is
fine.  Unfortunately, hitting any button on the remote completely
locks up the machine.

I'm concerned that ivti0 and nvidia are sharing an irq:

[root at myth ~]# cat /proc/interrupts

I also have these errors:

in /var/log/messages.  I've tried a lot of the archived tricks to get
rid of these. I'm currently running the ATRPM nvidia drivers:

nvidia-graphics-devices-1.0-5.fc6.at
nvidia-graphics9755-kmdl-2.6.20-1.2944.fc6-1.0_9755-86.fc6.at

nvidia-graphics9755-libs-1.0_9755-87.fc6
nvidia-graphics-helpers-0.0.22-23.fc6


And here is my xorg.conf:

Section "ServerLayout"
        Identifier     "Default Layout"

        Option      "MetaModes" "1024x768, 1024x768; 800x600, 800x600;
640x480, 640x480;"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        DefaultDepth     24
        Option "UseEvents" "True"
        SubSection "Display"
                Viewport   0 0
                Depth     24
        EndSubSection
EndSection

I have tried a number of permuations of  'Option "NVAGP" "1"'..

any help is much appreciated.
