This looks like a divide exception. Finding the source code
for the failing divide might help narrow down the problem. I
can't recreate your binary exactly so I can't find the failing
instruction from the eip value. But based on register values,
it looks like it is somewhere around line 334 of file
amd/agesa/f15tn/Proc/GNB/Modules/GnbInitTN/GfxGmcInitTN.c
You might be able to use the link map, disassembly, or debug
prints to figure out the exact source line that is failing.
Thanks,
