By default, kdump-tools does not reserve enough memory for a crashkernel on arm64. The smallest reservation I've been able to get away with on my test machine (a Cavium ThunderX crb1s) is 512M.

While kdump-tools currently supports architecture-specific configs, it currently has issues that I am attempting to address here:
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=863858

Adding an arm64 config before that is resolved in Debian may lead to upgrade complications, so I'd like to wait until is fixed before installing an arm64-specific config. This means that, for now, arm64 users will need to manually edit their /etc/default/grub.d/kdump-tools.default config to contain:

GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT crashkernel=1G-:512M"
