Title:
  Dell XPS 15 (9530) - Wifi hard blocked on startup

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  My Wifi seems to be hard blocked when powering my notebook and could
  not be unblocked via keyboard switch (Fn + print_screen) nor any other
  hardware key. Only if I go to suspend mode and resume the Wifi is
  unblocked.

  Laptop model is Dell XPS 15 (9530) with Intel 7260 AC Wifi card.

  I'm using Ubuntu 15.04, same problem with 14.04 LTS and 14.10. BIOS
  installed: A08 (also had this problem with A06 and A07). Wifi is
  working in Windows 8.1 without problems.

  Output of cat /sys/kernel/debug/dell_laptop before suspending:
