Ok, here's the deal - it looks like a corruption which causes a couple
of different backtraces with different functions in the call trace. I've
bisected tip:x86/cpu and the evildoers are:

x86/fpu: Fix FPU initialization

x86: Get rid of ->hard_math and all the FPU asm fu
I'll venture a guess and say that if you revert those, your .config

window. IMHO of course.
Thanks.
