Makes sense I messed up somewhere. This is the commit that causes
problems:

Merge branch 'topic/slab/earlyboot' of git://git./linux/kernel/git/penberg/slab-2.6


* 'topic/slab/earlyboot' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/slab-2.6:

  vgacon: use slab allocator instead of the bootmem allocator

  irq: use kcalloc() instead of the bootmem allocator

  sched: use slab in cpupri_init()

  sched: use alloc_cpumask_var() instead of alloc_bootmem_cpumask_var()

  memcg: don't use bootmem allocator in setup code

  irq/cpumask: make memoryless node zero happy

  x86: remove some alloc_bootmem_cpumask_var calling

  vt: use kzalloc() instead of the bootmem allocator

  sched: use kzalloc() instead of the bootmem allocator

  init: introduce mm_init()

  vmalloc: use kzalloc() instead of alloc_bootmem()

  slab: setup allocators earlier in the boot sequence

  bootmem: fix slab fallback on numa

  bootmem: use slab if bootmem is no longer available

Makes sense since it is very early in the boot I get the badness. Also, there is no mention of JFS in the above logs.

Cheers,
   Sean
