I've tried so many different kernels this last week that I've forgotten just how long I left the build without 8aac6270 running, but I'm pretty sure it included an overnight run last weekend. Given I have two identical machines that can reproduce it, I'll leave one running for a few days with that reverted just to see if it turns up.
(Though, I seem to be walking into other issues [like the perf overflow bug I reported last night] before seeing the lockups reproduce, so I'll keep an eye on it).
