I think I'd suggest the latter.  If the fix was brought by those ioapic
patches, the bug has always been latent as far as I could see.

I'm afraid that bisection would be pretty time consuming, also because
the bug didn't reproduce 100% for me (and at some point stopped
reproducing even on 3.10, causing some serious wtf...).
