[Bug 1529353] Re: NUC NUC5CPYH Does not boot on Ubuntu 15.10 (4.2.0-22-generic) most of the time

 

I'm a bit lost now, here's what I've done:

First tried bisecting vanilla kernel from linus tree and they seem to
work just fine upto 4.4-rc7 so this is something Ubuntu specific. I
tried also v4.4-rc7-wily from http://kernel.ubuntu.com/~kernel-
ppa/mainline/?C=N;O=D and problem is still there.

I can't use git://kernel.ubuntu.com/ubuntu/ubuntu-wily.git  because even
the first kernel tag won't work so I backed to
//kernel.ubuntu.com/ubuntu/ubuntu-vivid.git

I have git tags that I should bisect between and those are
Ubuntu-3.18.0-13.14 and Ubuntu-3.19.0-7.7  which will list with: git tag
command

But then I run into this problem (debian and debian.master directories
missing)
https://wiki.ubuntu.com/Kernel/KernelBisection#Why_did_the_folders_debian_and_debian.master_disappear.3F

and when I run 
git rev-list Ubuntu-3.19.0-7.7 | grep $(git log --pretty=oneline -1 Ubuntu-3.18.0-13.14 | cut -d' ' -f1)
as suggested here https://wiki.ubuntu.com/Kernel/KernelBisection#Commit_bisecting_Ubuntu_kernel_versions_across_non-linear_tags

I get no sha1 so that suggests that tags aren't linear.

And from here I looked for the git tags
http://people.canonical.com/~kernel/info/kernel-version-map.html
