To load a second stage kernel and execute a kexec re-boot or to work with kdump on ARM64 systems a series of patches to kexec-tools [2], which have not yet been merged upstream, are needed. Please update to the latest if you have been using an older version. To examine vmcore (/proc/vmcore), you should use - gdb v7.7 or later - crash v7.1.1 or later [1] https://git.kernel.org/cgit/linux/kernel/git/geoff/linux-kexec.git [2] https://git.kernel.org/cgit/linux/kernel/git/geoff/kexec-tools.git
kexec-tools is still passing "mem=" parameter to the crash dump kernel which causes it to crash with ACPI. You can revert commit "arm64: kdump: pass "mem=" parameter to a crash dump kernel" in kexec-tools.
Also, some version of the following patch from Pratyush is also still needed: https://github.com/pratyushanand/kexec-tools/commit/85f403cabb9ae0d7a37d1656a00fb609a9525086
