Thanks for the feedbacks so far. Resuming results :

*Martin* (BCM43142) - has the adapter working but from time to time it
shows the kernel back traces and "start" having erratic behaviour. 3.19
is still supported (unfortunately this driver is an external dkms driver
so we are working on a best effort basis here. I'm trying to understand
what is going on and maybe discuss with Broadcom. Thank you for the
kernel back trace, I will check bcmwl code and back trace and provide
feedback.

*Zethan* (BCM4352) - has the adapter working (is this correct ?) and
suspend started working (but card is not operational after suspension).
What about unloading and loading the kernel module right after
suspension, does it fix the issue ?

Please, try to unload these modules and then load wl module again (right
after first boot AND after suspension):

  # rmmod brcmsmac
  # rmmod ssb
  # rmmod bcma
  # rmmod wl

  # insmod wl

*Igor* (BCM???) - hasn't been able to reproduce the original problem
(this bug's description) and everything seems fine.

Title:
  14e4:4365 bcmwl-kernel source: fix for null pointer crash

Status in Dell Sputnik:
  Confirmed
Status in bcmwl package in Ubuntu:
  In Progress

Bug description:
  The bcmwl package as of now misses one patch for a bug that occurs
  with BCM43142 and possibly other broadcom chipsets that will look like
  random disconnects, poor wifi signal and kernel warnings, See also
  #1379524.

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches
  * add the following line to  /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf
  PATCH[7]="0014-null-pointer-crash.patch"
  * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom /usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.
