Kernel Panics

I'm having Kernel panics when I try and view some MPEG video files. Here are some snippets from zmdc.log...

I also have this scattered about in the log, but it seemed to go away once I set the camera to a maximum of 30fps...

Do you mean real kernel panics? I can't see anything odd in the logs. I would expect that if you are getting real panics (with all the attendant dumping of registers etc), it would most likely be in your video driver, in ffmpeg in the video generation (especially if you have a more recent CVS version) or if you are viewing them on the same machine then perhaps in your players. The driver is the most likely candidate as it's very difficult to generate panics from userspace programs.

I have had the computer restart when playing back mpeg with two seperate files. Once was when I used Firefox on the server itself, the other time was when I was using a remote computer. Both times I was playing back a clip and the machine restarted.

Do you mean a complete re-boot, or a re-start of the Xwindows system?
Do you have any last-gasp messages in /var/log/* or elsewhere?
I've seen Xwindows crash-and-restart caused by problems with the DRI module. Last time I had a machine that kept crashing and needing a reboot the problem turned out to be hardware - the memory had developed some sticky bits... :/

These are full reboots.

Hmm, it's not something like ffmpeg (or something else) being build for a particular Intel processor and you having an Athlon or something like that?

I am also getting these kernel panics.
It only happens when I am in MORECORD mode.
It is very odd.
Plus I am getting these errors as well.

I notice your card are very similar. I wonder if you are getting any conflicts between them, have you tried it with just the cameras on one card? Or even temporarily removing (and or moving) one of the cards?

I've never realized that.
It is all one card. It appears that the video and the audio channels have been enabled on the card.
I'm not quite sure how to prevent the audio driver from installing. Let me do some searching on the net.

I seemed to have fixed the errors or just preventing them.
By simply changing the frame capture rate to 15 instead of 21 the kernel panics have stopped.
What is odd, previous releases I was capturing @ over 30 fps and never saw this error.
however, I am happy with 15 fps.
