[Kernel-packages] [Bug 1758206] Re: Ubuntu 18.04 [ WSP DD2.2 with stop4 and stop5 enabled ]: kdump fails to capture dump when smt=2 or off.
Can you confirm the appropriate test kernel was booted with 'uname -a'?
You should see the text 'lp1758206' in the kernel name.
Also, could there be more the the three patches required that were
posted to the description:

[Kernel-packages] [Bug 1758206] Re: Ubuntu 18.04 [ WSP DD2.2 with stop4 and stop5 enabled ]: kdump fails to capture dump when smt=2 or off.
I built a Bionic test kernel with the three commits mentioned in the bug
description. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1758206
Can you test this kernel and see if it resolves this bug?
Note, to test this kernel, you need to install both the linux-image and
linux-image-extra .deb packages.
Thanks in advance!
