Brian Burch, thank you for providing the requested information. To keep
this simple, let this focus on just when you come up from a shutdown
(not resume from suspend), as resume from suspend is treated as a
separate problem.

Despite this, could you please answer the following questions:
+ Is this reproducible on your home WiFI network?
+ Does b43 provide a WORKAROUND as outlined in https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx ?
+ Did this happen in a prior Ubuntu/wl version?
+ Which WiFi hotspot would be most convenient for you to do testing on?
+ At the most convenient WiFi hotspot, could you please test the later version of wl in Utopic (live environment is fine) via http://releases.ubuntu.com/utopic/ and advise if this is reproducible?

Title:
  14e4:4315 [Dell Studio 1558] Broadcom wifi crash in bcmwl-kernel-
  source cfg80211

Status in “bcmwl” package in Ubuntu:
  Incomplete

  Description: Ubuntu 14.04.1 LTS

  3) What is expected to happen with my Dell Studio 1558 is that when
  using wifi hotspots away from home, it works without problem.

  4) What happens instead is that the the system never makes a connection, and there is a crash in syslog:

  The system is resuming after suspend. However, I have seen similar
  crashes after simply powering on, and in more than one hot spot.
