Upon further testing Lunar kernel 6.2 seems not be affected. I'll
investigate further to find out why.

kdump fails on arm64, on machines with a lot of memory when offeset is not
specified,
e.g when /etc/default/grub.d/kdump-tools.cfg looks like:
GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT crashkernel=4G"
If kdump-tools.cfg specifies
