OK, did all of that. I should probably note that in both cases, the kernel is loaded/booted by using kexec. Both boot logs are captured generated via netconsole.
The failing boot log is netcon-4409.log. The working boot log (CONFIG_NUMA=y) is netcon-4410.log. Enabling CONFIG_NUMA makes the following changes:
