I can't say for sure, but this looks much like the GbE and/or Firmware
Descriptor regions of the BIOS flash are corrupted. If in doubt, you can
generate a layout file for flashrom from the backup of the vendor BIOS
with `ifdtool -f` (see util/ifdtool/ in the coreboot tree). And flash
back these selected regions with `flashrom -l layoutfile -i fd -i gbe
...` from the backup.
