I have an early 2008 Mac Pro running CS6 and 10.8.2. My usual workflow is burning two hour multi-cam live performances to DVD. Usually this is two cameras of DV, one camera of AVCHD, all in a DV timeline.
Lately I've been trying to burn DV timelines of nothing but AVCHD footage, and somewhere through the rendering process I always get a kernel panic. This happens with different projects, footage from different cameras (I'm using a Panasonic AG-AC130 or HMC40), whether I'm using Encore CS5 or CS6. The projects never finish. It seems to get 50-75% through rendering video before crashing. Rendering these projects on my MacBook Pro work just fine (though much slower). Timelines where it's not 100% AVCHD are still working fine.
I had began having kernel panics unrelated to Encore, but traced this back to a heat issue. It's an old machine after all. After installing smcFanControl, this problem has gone away. I don't normally burn timelines of nothing but AVCHD, but I'm certain there was a time in the past I was able to burn these without issue. I monitor my system temperature during rendering and I'm somewhat confident that's not what's crashing the system.
The top part of my latest crash report is listed below. Can anyone help me figure out what's going on?
