hm, that's a bit weird - nothing really should have broken it. Could you 
try to do a specific bisection of sched-devel.git:

   http://people.redhat.com/mingo/sched-devel.git/README

it's just a handful of commits so it should be relatively quick to 
figure out. My only guess would be:

  Subject: sched: make early bootup sched_clock() use safer

but i think this has been ruled out before ...
