Hi,
I got this stacktrace shortly after bootup. I am disabling the two
hyper-threaded cores in my startup scripts so possibly that was the
trigger, at least per earlier report from Fernando Soto on Jul 08 2013:
https://lkml.org/lkml/2013/7/8/301
I don't see his name in this patch series which Google bring to me:
Re: [PATCH v1 2/3] SMP: simpilify function generic_smp_call_function_single_interrupt()
does the patch fix the issue? Are you aware of the issue? That is why
I CCed all of you. ;-) Please, somebody add to Cc: also Fernando, I cannot
find his email address in SPAM-protected email archives. surely you have
his original email in your Inbox or Trash. Thanks.
My stacktrace from 3.10.10 is:

Hi Martin,
I don't think the mentioned patch could solve your problem.
The warning messages implies some issues in CPU hotplug, need more
investigation.
Regards!
