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. [Test Case] ubuntu@ubuntu:~$ sudo file /boot/vmlinuz-4.9.0-15-generic /boot/vmlinuz-4.9.0-15-generic: gzip compressed data, max compression, from Unix ubuntu@ubuntu:~$ sudo kexec -d -l /boot/vmlinuz-4.9.0-15-generic -t Image arch_process_options:141: command_line: (null) arch_process_options:143: initrd: (null) arch_process_options:144: dtb: (null) kernel: 0xffff8ff61010 kernel_size: 0x6ee18b get_memory_ranges_iomem_cb: 0000000040000000 - 00000000ffffbfff : System RAM get_memory_ranges_iomem_cb: 0000000100000000 - 000000013858ffff : System RAM get_memory_ranges_iomem_cb: 0000000138750000 - 000000013bc1ffff : System RAM get_memory_ranges_iomem_cb: 000000013c000000 - 000000013fffffff : System RAM image_arm64_probe: Bad arm64 image header. elf_arm64_probe: Not an ELF executable. image_arm64_probe: Bad arm64 image header. Cannot determine the file type of /boot/vmlinuz-4.9.0-15-generic [Regression Risk] kexec-tools did not support arm64 until zesty so, assuming the fix is localized to arm64 code, regression risk is negligible.
