I have a feeling that it is coming from my video cardsthe cr8802_irq and so on would hint to that direction. Other than that I have no need for lirc specific modules I could blacklist them, but for the cr8802_irq I am not sure what it is for. I have the firmware for this revision of cards under /lib/firmware and actually it has worked fine so far but now it is getting twitchy. Is the reason in my video card hardware or just on the driver side?

It certainly looks like it's related to the video card:

Why not blacklist all the cx88* drivers and see if that helps?

If the system's getting increasingly unstable and you haven't upgraded/patched the kernel, a hardware issue seems likely to be the underlying cause.

The call trace is after the real error. Often you can get to see more with Shift_PgUp.

That said, there seems a lot of cpu stuff in the call trace, along with IRQs. Checking logs might get you what they're hooked up to, and more of the error.
