I am getting no kernel panics on the console. It crashed again just now after I left the machine idle for lunch. I had to force restart it. I usually have mail, safari, Microsoft Word and maybe iTunes running. I don't have any tweaks installed. The machine is freezing regardless of what I do.
I did reinstall Mt Lion, not a clean install but just a reinstall, last night, but that changed nothing.
Here is the last thing on my console before it crashed, but it seems to be different every time
