Subject: SLUB regression in current Linus

I started experiencing a boot hang in 2.6.39+, and bisected it to this 
change:

commit 442b06bcea23a01934d3da7ec5898fa154a6cafb
Author: Christoph Lameter <cl@...ux.com>
Date:   Tue May 17 16:29:31 2011 -0500

    slub: Remove node check in slab_free


Reverting the patch appears to fix the hang for me, although I'm not sure 
what the actual problem is.

This is on a quad-core Opteron (1352). Let me know if you need any further 
info.
