Hey alright 2.6.31-rc6 booted.

I must admit, I've been afraid of doing
a git bisect for some time now. but after learning
to do a bisect, I cant see a better solution to finding a
bug(biggest issue I see is having a huge .config).

Anyways the culprit for my issue is this commit:

af6af30c0fcd77e621638e53ef8b176bca8bd3b4

reverting this on rc6 booted the machine up.
