That was definitely not my intention...

I have NO evidence whatsoever that the new driver would fix my problem, 
i.e. kernel crashes in certain unidentified kinds of wifi hotspots.

However, I have good evidence that the new driver installs and runs OK 
on the 14.04 LTS 3.13.0-40-lowlatency kernel.

My suggestion is that it would be good from many aspects (especially 
support) to accelerate testing so the new driver could be added to the 
14.04 repository without making anything worse. The advantage would be 
to have the same driver on several releases to shake out any remaining bugs.

If my bug happened to be fixed as a side-effect, that would be nice. 
However, the main issue would be the standardisation of the latest 
driver across current ubuntu releases.

Regards,

Brian

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

  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.
