I was apparently comparing apples to oranges. Given the fatal configuration options (DEBUG_SLAB and/or DEBUG_PAGEALLOC) 2.6.37-rc1 fails the same as a more recent snapshot of Linus's tree. I updated my view today, and it still fails to boot with DEBUG_SLAB and/or DEBUG_PAGEALLOC, and boots OK without them. It also fails to boot with SLUB and SLUB_DEBUG enabled, even with SLUB_DEBUG_ON disabled. Ben has access to my system, and will look at it in a few days.
