hm, is this SMP? Alpha uses asm-generic/percpu.h. One "early bootup" 
effect on Alpha that i can think of could have been this family of 

 commit acdac87202a408133ee8f7985076de9d2e0dc5ab

     percpu: make the asm-generic/percpu.h more "generic"

you wont be able to revert this patch cleanly, perhaps try to compile 
commit cf8fa920cb4271f17e0265c863d64bea1b31941a and see whether it

if that doesnt help then i guess it's the bisection of 9000+ commits :-/
