Stupid Windows 8 mistake corrupted my Linux partition and its been a year since I've first installed Gentoo so I decided to rebuild it.

I've been using geek-sources as before (with TuxOnIce, BFQ, UKSM) but it seems to occur for pf-sources and ck-sources. When I boot a system with CONFIG_SCHED_BFS, I get a kernel bug stating that it cannot "dereference a NULL pointer", but other than that there does not seem to be much useful information. I will copy it and dump it in entirety when I have time. Booting without BFS works perfectly fine, but I would certainly like to utilize the ck patchset. ck-sources seems to be stuck at 3.14 because gentoo-sources is; but no 3.14 sources appear to work with the BFS patch.

Kernel Config: http://pastebin.com/g1f1FirD
