Marking as "High" as the work around for this bug, once a user is bit by
it, is to have someone in the datacenter physically power cycle a
machine.

Title:
  IPMI commands are sent / queried too fast

Status in OpenStack Bare Metal Provisioning Service (Ironic):
  In Progress
Status in OpenStack Compute (Nova):
  New

Bug description:
  http://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/second-gen-interface-spec-v2.pdf has this in it:
  ---
  1.7.32
  Configuration Interfaces
  ...
   In some implementations, changes to configuration parameters may take
  effect immediately. Thus, a remote application should be careful when setting parameters that could cause the
  application to become disconnected from the BMC.

  For the purpose of conformance checking, up to 5 seconds will be allowed between the time a parameter is
  changed to when it must have taken effect.
  ----

  We've seen repeated cases of BMCs locking up or getting confused with
  high frequency polling - it might be an idea to wait 5 seconds - the
  required max time between change and effect - rather than the polling
  interval we use today.
