Hi Liming Wang,

Title:
  Atheros AR8161[1969:1091] and AR8162 [1969:1090] mac address would
  change after powered off for a while

Status in HWE Next Project:
  Confirmed
Status in linux-lts-trusty package in Ubuntu:
  New

Bug description:
  CID: 201202-10508 
  CID: 201202-10511
  CID: 201202-10527

  The MAC address would change after you power off the system for a
  while (few days)

  201202-10508 and 201202-10511 equipped with AR8162 [1969:1090]
  201202-10527 equipped with AR8161[1969:1091]

  I found this issue when trying to install 12.04.5 via PXE network installation.
  The MAC address changing pattern is interesting, there is a common address they will change into - 00:13:74:00:00:00

  This looks like a HW issue, but I'm not very confident about it.

  Maybe not a big deal, but this issue would prevent these system from
  being selected into our SRU pool, the worse scenario is that this
  system is attached to a MAC-address-registered network (my dormitory
  network back into university require users to register they MAC
  address)
