Title:
  Microcode SW error detected.  Restarting 0x2000000 on connecting to AC
  network with iwlwifi-7265-ucode-25.228.9.0

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  When trying to connect to an 802.11AC network using an Intel 7265 with
  firmware iwlwifi-7265-ucode-25.228.9.0 on kernel 3.16.0-38-generic
  #52~14.04.1-Ubuntu, the error " Microcode SW error detected.
  Restarting 0x2000000." is received, the card crashes and can't connect
  to the network.

  The same card/driver/firmware combination performs well on 2.4GHz
  networks, and also 802.11a.
