HI S2k, sorry I hadn't logged onto the site in a few days. I see the cpu panic in the log you have submitted. If there is no panic.log in the /library/log then there isn't one. Alternatively you can search using the search utility for it.
Is the log that you posted the entire log ? As I can see the kernel panic in the header, but don't see the error. Can you post the full error log?
