--- Comment #31 from Maarten Lankhorst <bugs at mblankhorst.nl> ---
I suspect the issue is commit

    x86/apic: Get rid of multi CPU affinity

But my bisect likely failed since I can't reproduce it now on that commit any
more, signing off for now..

What did work was reverting the whole pull for apic, which appears to be doable
cleanly, so maybe someone else can retry. :)
