Results are persistent, git bisect points to:
commit b24c2a925a9837cccf54d50aeac22ba0cbc15455 Author: Yinghai Lu <yinghai@kernel.org> Date: Tue Nov 24 02:48:18 2009 -0800
x86: Move find_smp_config() earlier and avoid bootmem usage
which appears consistent with the panic(). Reverting that does indeed make current -git boot properly.
