Bug Description

Description: Ubuntu 20.04.3 LTS
Release: 20.04

The linux-generic-hwe-20.04 5.13 Kernels are compiled with

#CONFIG_KERNEL_GZIP is not set
CONFIG_KERNEL_ZSTD=y

preventing Xen 4.13.x / 4.14.x from booting into Dom0. After compiling the kernel by myself using

CONFIG_KERNEL_GZIP=y
#CONFIG_KERNEL_ZSTD is not set

it works as expected. Kernel boots and Xen is working as intended. Please revert to CONFIG_KERNEL_GZIP=y like in the former HWE (5.11?) series not having this problem.

Thank you
