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.
