Title:
  wired network disabled after resume (AR9485)

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  I have both a wired network and wireless. On first boot both are
  functional, but on resuming from sleep the wired controller is
  disabled (wireless still works). This behaviour started with the
  latest kernel installed yesterday.

  From syslog on resume
