I had posted this on Ask Ubuntu orinally and was pointed here. My original post is at: https://askubuntu.com/questions/732248/14-04-latest-3-19-kernel- causes-kernel-panick-3-19-0-49-generic/732613#732613 I didn't use the ubuntu-bug linux command because that would report on my existing working kernel rather than the new one. For the time being I just have to manually select older kernels.
