Hi there,

My computer (G5 2.5) is kernel panicking frequently on shutdown.
Could someone please take a peek at this log and let me know if anything looks fishy?

Get you original Software restore disks that came along with your Mac. The find the one that has the words "Hardware Test" and use that disk instructions to run a hardware test on your Mac. If I read the log right, it may look like your CPU number 1 is diving to failure. Sorry to be the deliverer of bad news.
 
Your logs don't show anything related to a software problem.

My guess, bad memory, Logic Board or hard drive,

If you've added memory, take it out and see if you still get the panics.

As Satcomer said, use the Hardware test if you have it.
 
Frame not mapped or invalid refers to a memory problem. RAM is divided into frames and a frame is mapped to physical(or virtual) RAM by the operating system.
