Bug description:
== SRU Justification ==
IBM has requested these three commits in Artful. In Artful, kdump fails to
capture dump when smt=2 or off.
Including these three commits allows kdump to work properly.
== Fixes ==
4388c9b3a6ee ("powerpc: Do not send system reset request through the oops
path")
04b9c96eae72 ("powerpc/crash: Remove the test for cpu_online in the IPI
callback")
4552d128c26e ("powerpc: System reset avoid interleaving oops using die
synchronisation")
== Regression Potential ==
Low. Fixes are limited to powerpc.
== Test Case ==
A test kernel was built with these patches and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.

[Kernel-packages] [Bug 1776211] Re: kdump fails to take dump with smt set to 2, hmc dumpstart
I built an Artful test kernel with the three patches posted in the description. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1776211 Can you test this kernel and see if it resolves this bug? Note about installing test kernels: • If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages. • If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-unsigned .deb packages.
