OSX Kernal panic or restarting itself automatically

Hi guys,

need some help here.

Im running OSX 10.5.8
early 2008 octo Macpro 2.8
16GB OWC Ram
Radeon 2600 graphic card
Boot Drive Velociraptor 300GB
Data drives 2 x 1TB WD black
Itunes Drive Stock Mac 320GB (seagate)


for the past 3 weeks it has randomly restarted itself. And once in a while with Kernel panic. I tried to repair its permission but it Onyx Crashed while doing so. Resetting PRAM and SMC is useless.
Therefore I decided to do a fresh install of Mac OSX.

However the problem persists Same ****.... restarting itself automatically... and kernel panic right after it finish booting up...

The following is the log file from the most recent kernel panic right after finishing booting up. help HELP HELP!!!

I failed to repair permissions with DW or Onyx, but managed to do it with Disk Utility. So far so good.... fingers crossed X

by the way anybody knows what the above log means?

thanks in advance!
