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.
