Title:
  CPU lockup on HP Proliant DL380 Gen9 servers

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Over the past 3-ish weeks we've had 3 seperate HP Proliant DL380 Gen9
  servers lock up with a similar looking cpu lockup bug.  All 3 of these
  servers are nova-compute nodes in an OpenStack cluster, with a
  reasonable amount of load on them.  The symptoms are the load shoots
  up into the hundreds, and ps stops returning.

  I've attached lspci -vnvn and 3 sets of syslog message traces that we
  grabbed on each of the 3 times it has crashed.

  $ cat /proc/version_signature 
  Ubuntu 3.16.0-49.65~14.04.1-generic 3.16.7-ckt15

  Please let us know if you need any further information.
