Not noise at all! Yesternight i triggered a different boot crash myself and
bisected it down to:
f88731e3068f9d1392ba71cc9f50f035d26a0d4f x86, alternatives: Use 16-bit numbers for cpufeature index
... which was included in your git log as well.
So i am quite sure that commit has caused your boot crash as well!
Thanks,
Ingo
