[Linux 3.5] kernel BUG at mm/slub.c:3474!

[Yogesh Ashok Powar]

Hello All,

I am seeing the bug_on being hit on ARM  Kirkwood based board.
I am on Linux 3.5 stable tree.

Please see oops at the bottom of the mail.

The kernel's .config is shared at http://nopaste.info/37d9019bf5.html

Thanks
Yogesh
