Kernil Panic every few hours!

My MacBook Pro is giving me a kernel panic every few hours. Here's the log, help please!

Do you have any peripherals connected to the machine? Disconnect everything but the keyboard and mouse and see if the problems stop. Your error log references I/O, so that's a good thing to look at. Also, if this is a tower, check your PCI cards, they may be prompting the errors as well.

If you can, it's also usually a good idea to start up from another source (external drive, CD, etc) and see if the problems persist. If not, it could be software.
