--- Comment #11 from Lyude Paul <cpaul at redhat.com> ---
So for whatever reason I'm having no luck with getting this bug to show itself
even once on this machine. I'm probably going to look over the code a few times
and see if I can guess what fixes it by sending a couple of patches to the
trybot, but it would be a lot easier if I could actually see it here…

So, I have one theory as to why I'm not seeing this with my NUC: the machines
I've seen logs from on this bug report have multiple cores, while mine only has
a single core. I'm thinking it's possible not having multiple cores here means
there's almost no chance of the hotplug polling running at the same time as any
of the other resume tasks in the kernel. I'm trying to get my hands on another
NUC with more then one processor, but for the time being would one of you be
able to run this test with "maxcpus=1" added to the kernel cmdline and see if
the problem still happens?
