Title:
  ledmon does not work in Ubuntu 14.04

Status in The Dell PowerEdge project:
  In Progress
Status in “ledmon” package in Ubuntu:
  Fix Released
Status in “ledmon” source package in Trusty:
  Triaged

Bug description:
  ledmon will not work in Ubuntu 14.04, due to a change in kernel 3.13.

  I've tested this with ICH10R and C600/X79 chipset.

  Symptoms: ledctl gives 'enclosure management not supported' on
  supported hardware.

  This problem has just been fixed by upstream, see this patch:

  http://sourceforge.net/p/ledmon/code/ci/6f7d38bbe5d7b13c84987cf3b3b550a11c39392e/

  Please update the Ubuntu package to include this patch, so ledmon
  works again.

  Installed package: ledmon 0.79-0.2
  ~$ lsb_release -rd
  Description:	Ubuntu 14.04 LTS
  Release:	14.04

  [Impact]

   * The type of libahci parameter ahci_em_messages was changed from int to
  bool in kernel v3.13, which caused AHCI HBAs to not be detected
  properly.

   * This basically means that ledmon no longer works in 14.04

  [Test Case]

   * install ledmon and start up the openipmi service

   * The following ledctl commands should no longer give 'enclosure
  management not supported' on supported hardware with the fix in place:

  sudo ledctl locate=/dev/nvme0n1
  sudo ledctl locate=/dev/rssda
  sudo ledctl locate_off=/dev/rssda
  sudo ledctl locate_off=/dev/nvme0n1

  [Regression Potential]

   * Low, as this bug affects 14.04 and higher due to the newer kernel
  version.  Systems running the older kernel releases should be fine.
