Comment 43 for bug 1816947

I'm trying to pinpoint the kernel version in which the bug appeared.

So, following the bisection guide, I checked the releases of the artful linux source package (https://launchpad.net/ubuntu/artful/+source/linux)

From my previous tests, artcul livecd worked ok, and it reported kernel 4.13.0-21

I tried installing the previous release to that version: (I couldn't find the 4.31.0-21 version)

linux-headers-4.13.0-19_4.13.0-19.22_all.deb
linux-headers-4.13.0-19-generic_4.13.0-19.22_amd64.deb
linux-image-4.13.0-19-generic_4.13.0-19.22_amd64.deb

(downloaded from https://launchpad.net/ubuntu/+source/linux/4.13.0-19.22)

I installed them with sudo dpkg -i *.deb

I assumed they should work ok, because they are before a version that worked ok, but they present the same bug. Every other version I tried like this did the same.

Then I tried with several versions from the upstream kernels (from https://wiki.ubuntu.com/Kernel/MainlineBuilds) an they all worked fine, even the msot recent ones. So this must be a bug introduces by ubuntu.

I'm kind of stuck. I'd like to be able to reproduce the working kernel from artful livecd and then start bisecting from there.

Any other clue you could give me?
