To add to this request, I set up another wireless card as an AP, and
iwlwifi was able to connect to it, so I think the bug is between iwlwifi
on client side, and rtl8192cu on the hostapd side.  (Bus 001 Device 004:
ID 0bda:8178 Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN
Adapter).

Title:
  iwlwifi will not connect with hostapd access point

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 12.04, 14.04, and 14.10 seem to have this issue.

  Everything else that I own will..... and I even stuck an atheros card
  in my other server running ubuntu, and that connected just fine... but
  anything that I have on iwlwifi refuses to connect.

  syslog for wpa_supplicant shows:

  and that repeats.

  I can also connect to a linksys router I have acting as an access
  point, but when going to this new hostapd access point, these two
  setups do not agree.  I have also tried with Ubuntu 14.10/3.16 kernel,
  and to test a newer kernel version, Fedora 21 with 3.17+.  Same thing
  happens.  Seems to be specific to iwlwifi and Linux.
