You might want to try the patch in RT #49890 - it covers all the issues 
I ran into with Fedora rawhide with a 2.6.20 rc1 based kernel.

Besides the refrigerator changes (no more PF_FREEZE, need to include 
freezer.h), there's a change in the INIT_WORK interface and a 
replacement of SLAB_KERNEL with GFP_KERNEL.
