Bug description:
== SRU Justification ==
Kernel crashes when installation of Ubuntu-16.04.3 with HWE (ISO).
Same observation while booting to 4.10.0-28 HWE kerenl of Ubuntu-16.04.3
and 4.10.0-33 HWE as well.
Seen only with 4.10 HWE kernels of Ubuntu-16.04.3. 4.4 kernels of
Ubuntu-16.04.3 works fine. Daily builds of Ubuntu Server 17.10 works fine.
Reducing the core count to <26 cores helps here. Boot & installation of
HWE-kernel works fine.
This bug was introduced by commit:
dc6db24d2476 ("x86/acpi: Set persistent cpuid <-> nodeid mapping when
booting")
It is resolved by reverting commit dc6db24d2476, which was done in mainline
by
commit c962cff17df as of v4.11-rc3.
There are three additiona commits introduced by the same patch author when
commit c962cff17df was submitted. However, it was confirmed that only the
single
revert is needed to fix this particular bug. Upstream thread:
https://lkml.org/lkml/2017/2/20/66
== Fix ==
commit c962cff17dfa11f4a8227ac16de2b28aea3312e4
Author: Dou Liyang
Date: Fri Mar 3 16:02:23 2017 +0800
Revert "x86/acpi: Set persistent cpuid <-> nodeid mapping when
booting"
== Regression Potential ==
This is reverting a commit that introduced a bug. This commit has also
been reverted upstream.
== Test Case ==
A test kernel was built with this patch and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.
Setup:
Dell PowerEdge R940 having 2 socket populated with 28 cores.
Impact:
This is a boot and installation failure for R940 users having 2 socket x 28
cores.
Requesting an SRU for the fix.
Steps:
1. Setup a Dell PowerEdge R940 with 28 cores CPUs on 2 sockets.
2. Start installation of Ubuntu-16.04.3 with HWE kernel.
3. Observe the screen remains blank. Console logs indicate kernel crash.
Additional Info:
* Seen only with 4.10 HWE kernels of Ubuntu-16.04.3.
4.4 kernels of Ubuntu-16.04.3 works fine. Daily builds of Ubuntu Server
17.10 works fine.
* Reducing the core count to <26 cores helps here. Boot & installation
of HWE-kernel works fine.
* Attaching the console log and acpidump from the setup.

Kernel crashes when installation of Ubuntu-16.04.3 with HWE (ISO).
Same observation while booting to 4.10.0-28 HWE kerenl of Ubuntu-16.04.3
and 4.10.0-33 HWE as well.
Seen only with 4.10 HWE kernels of Ubuntu-16.04.3. 4.4 kernels of
Ubuntu-16.04.3 works fine. Daily builds of Ubuntu Server 17.10 works fine.
Reducing the core count to <26 cores helps here. Boot & installation of
HWE-kernel works fine.
This bug was introduced by commit:
dc6db24d2476 ("x86/acpi: Set persistent cpuid <-> nodeid mapping when
booting")
It is resolved by reverting commit dc6db24d2476, which was done in mainline
by
commit c962cff17df as of v4.11-rc3.
There are three additiona commits introduced by the same patch author when
commit c962cff17df was submitted. However, it was confirmed that only the
single
revert is needed to fix this particular bug. Upstream thread:

[Kernel-packages] [Bug 1719697] Re: Boot/Installation crash of Ubuntu-16.04.3 HWE kernel on R940
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
zesty' to 'verification-done-zesty'. If the problem still exists, change
the tag 'verification-needed-zesty' to 'verification-failed-zesty'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Requesting an SRU for the fix.
Steps:
1. Setup a Dell PowerEdge R940 with 28 cores CPUs on 2 sockets.
2. Start installation of Ubuntu-16.04.3 with HWE kernel.
3. Observe the screen remains blank. Console logs indicate kernel crash.
Additional Info:
* Seen only with 4.10 HWE kernels of Ubuntu-16.04.3.
4.4 kernels of Ubuntu-16.04.3 works fine. Daily builds of Ubuntu Server
17.10 works fine.
* Reducing the core count to <26 cores helps here. Boot & installation
of HWE-kernel works fine.
* Attaching the console log and acpidump from the setup.
