Hi, Josh. In order to disable CONFIG_HOTPLUG_CPU, we also need to turn off CONFIG_HIBERNATION, CONFIG_SUSPEND and everything that relies on them. Are you ok with that?
I'm attaching the patch with the config changes if you want to take a closer look at it. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-azure in Ubuntu. https://bugs.launchpad.net/bugs/1776293 Title: [Hyper-V] Disable CONFIG_HOTPLUG_CPU in linux-azure Status in linux-azure package in Ubuntu: New Status in linux-azure source package in Bionic: In Progress Bug description: While Hyper-V may present all potential CPUs via ACPI MADT, CPU add/remove is not supported. This results in kernel data structures created for the largest potential size based on the number of CPUs when those CPUs will never be added during the time the guest is up (it can certainly be resized when it's down and deallocated).
