Does reverting the following patch make the panic go away?

http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.16-rc1/2.6.16-rc1-mm3/broken-out/slab-cache_estimate-cleanup.patch

If not, you can safely revert the following patches one by one in reverse order:

slab-distinguish-between-object-and-buffer-size.patch

slab-have-index_of-bug-at-compile-time.patch
slab-cache_estimate-cleanup.patch

slab-reduce-inlining.patch
slab-extract-virt_to_cacheslab.patch
slab-rename-ac_data-to-cpu_cache_get.patch
slab-replace-kmem_cache_t-with-struct-kmem_cache.patch
