Title:
  Broadcom wifi crash in bcmwl-kernel-source cfg80211

Status in “bcmwl” package in Ubuntu:
  Incomplete

Bug description:
  lspci shows: Network controller: Broadcom Corporation BCM4312
  802.11b/g LP-PHY (rev 01)

  lsb_release: Ubuntu 14.04.1 LTS (actually UbuntuStudio)

  Linux version 3.13.0-34-lowlatency

  Dell Studio 1558 with Intel CPU in i386 mode and four CPUs.

  Most of the time wifi works perfectly. Occasionally, when using wifi
  hotspots away from home, the system never makes a connection. Usually
  I see similar stack traces in the syslog, but the attached extract is
  the only example I have to hand.

  The system is resuming after suspend, but I do not believe that aspect
  is relevant. I have seen similar crashes after powering on, and (to
  repeat myself) in more than one hot spot. I suspect there is an edge
  case in negotiating with some wifi routers that is not handled
  properly. (Perhaps I am prejudiced, but I get the feeling that the
  problem routers are in iPhone-friendly environments).
