Regular & Persistent Kernel Trace Dumps

For the past number of months, I get regular dumps to log similar to those below. (I've also attached a full log file)

 

Sometimes, these result in a full server crash/freeze requiring reboot.

 

Any pointers as to where the cause may lie would be greatly appreciated;

    Thanks

     

    Tried that but to no avail (it ran really quickly and didn't seem to do very much)

     

    Anyway, I think this is a hardware issue - I'm having trouble with some SATA ports and have a new MB on order to see if that will resolve things.
