[Impact]
kexec-tools will not load a compressed kernel on arm64. Ubuntu ships compressed kernel images on arm64 starting with 16.10 (and hwe kernels for 16.04). A workaround is to manually decompress the kernel before loading it, but this is not supported by the use-kexec-for-reboot-by-default feature of the kexec-tools package.

[Regression Risk]
kexec-tools did not support arm64 until zesty so, assuming the fix is localized to arm64 code, regression risk is negligible. |
