Hi Chris,

Since the original good and bad versions vary in releases, and as I understood releases split to different git repositories, I thought it will help first if I do kernel release bisect to understand which release went wrong.

So, I used the bisect logic to manually download kernel binaries, install and try till I find the last good kernel release. But kernel versioning confused me a bit at the end and I am hoping you can help me figure it out.

So I started from 3.11.0.23 being the known GOOD version, and 3.13.11.09 being my attempted BAD version.

I used http://kernel.ubuntu.com/~kernel-ppa/mainline/ as the source of binary releases.

Since I didn't clearly understand the versioning I also decided to try the 3.11.10.15 which was also GOOD. From that on, I did a bisect logic between 3.11.10.15 - 3.13.11.09. It turned out these was broken quite long back!

So to summarize my results (at the bottom I am copying the full bisect test details):
LAST known good release: 3.11.10.15 (Here I assumed 3.12.0-rc1 immidiately follows this release, but I can be wrong, see further.).

But then I browsed the following URL and as I understood the trusty rc1 didn't really start on top of 3.11.10.15 but rather was branched off of 3.11.0-12.19. Is this correct? If so, it confuses me a bit now.

Given that 3.11.0-23 is GOOD, I wonder did all the changes from 3.11.0.12-3.11.0.23 also go into trusty (or maybe even vise versa, backported from trusty)?

What should I do next? my last known good version and first known bad version are still split between git repos sounds like.

The full details of my bisect test if will help:
