Bug Description
SRU Justification
[Impact]
Memory hot-plugging is not working with public cloud-images. Error with dmesg shows:
[ 184.544535] acpi PNP0C80:00: Enumeration failure
checking kernel configuration:
root@ubuntu:/boot# uname -r
5.4.0-1038-kvm
root@ubuntu:/boot# grep CONFIG_
# CONFIG_
Obviously the necessary kernel configuration for ACPI memory hotplug is missing.
root@ubuntu:~# cat /etc/cloud/

[Test Plan]
Boot a kernel with CONFIG_
[Where problems could occur]
Adding memory could fail, or cause other configurations issues. Regressions seem unlikely since this config option is enabled in all cloud kernels except linux-azure.

Marking affects linux, so the kernel folks can weigh in on this.
