The other trace is a kernel bug. lt is included below.

It is true the hardware is a bit old, but I freshly assembled the system.
The power supply is new, everything has been re-seated.
I will be updating the hardware eventually, but I picked this hardware
because it is low power (@120watts), server grade, has ecc memory,
and has pcix- slots, which my ethernet card and 8 port sata controller need.

For what it is worth, the ethernet card is an intel  pro1000-mt.
