Let me start by stating that this post is extremely similar to this other post that was made a year ago but its the specifics that have changed and I want to double check if I should file a bug report, or if there is something else I should do first to try and fix my kernel installation.

I've updated my computer and when I boot the latest kernel I am greeted by a purple screen. When I try to run recovery mode in that kernel, I am greeted by a kernel panic output.

I tried re-installing the latest 3.19 kernel by using the advice given here. The output of which is below (in case there is any useful information).

For now I can just keep booting off the old kernel, but I am tempted to upgrade to 4.2 by executing:

sudo apt-get install --install-recommends \
linux-generic-lts-wily

This has worked on a desktop I was re-setting up anyway and I wanted to see if it would work. It's interesting that the HWE docs state that this is okay for the server and doesn't mention it for the desktop which is why I've been holding off.


Update 11 Feb 2016

I tried installing the 4.2 kernel and got the same issue, so I don't think it's something to do with the kernel. I would love some advice on diagnosing this issue. Otherwise it looks like I need to perform a full reinstallation.

Kernel panics in Ubuntu's official kernels should almost always be reported to the kernel bug tracker on Launchpad, where they may be escalated to upstream bug trackers if necessary – unless of course you find a similar existing report.

I believe this holds true in your case.
