Updated the mainboard UEFI to latest version but am still getting the 
same kernel page fault.

I compiled "options DDB" and "options GDB" into the generic kernel.  
After rebooting and entering DDB I get the following from various commands:

On bootup I am now getting the following:

real memory = 8589934592 (8192 MB)
avail memory = 8198332416 (7818 MB)
Event timer "LAPIC" quality 600

Typing "s" and "c" at the db prompt gives the following:

db> s

db> c

And trace gives me the following output:
