The problem appeared in the 3.18 merge window. I bisected the problem (between v3.17 and v3.18-rc1) and I found the following commit responsible for the broken boot. commit 12220dea07f1ac6ac717707104773d771c3f3077 Author: Joonsoo Kim Date: Thu Oct 9 15:26:24 2014 -0700 mm/slab: support slab merge Reverting my tree back to the parent of that commit 423c929cbbecc60e9c407f9048e58f5422f7995d (" mm/slab_common: commonize slab merge logic") restores the boot for me. I don't quite understand the commit yet so let me know if you need more information to debug this problem Here is the kernel log of the failed boot.
