You point is valid, maybe it's better to check if Zesty has this issue.

Thanks for the follow up!

[Joseph Salisbury]

Yakkety is actually going to be EOL this week.  It might be best to see
if this bug exists in current and newer releases.  Do you know if this
bug happens with the Zesty kernel?

I built a v2 of the test kernel.  It can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1687779/

Can you test this kernel and see if it resolves this bug?

[Kernel-packages] [Bug 1687779] Re: Ubuntu 16.04.2: kdump is not working in 4.8.0-46 kernel

[Joseph Salisbury]

I built a Xenial test kernel with a pick of commit 6d6daa20945f.  The
test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1687779/

Can you test this kernel and see if it resolves this bug?
