This can continue to break kdump in certain conditions. [Test Case] sudo apt install linux-crashdump echo 'GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT crashkernel=512M"' | \ sudo tee /etc/default/grub.d/kdump-tools.cfg sudo update-grub sudo reboot echo 1 | sudo tee /proc/sys/kernel/sysrq echo c | sudo tee /proc/sysrq-trigger [Fix] 582a32e708823 efi/arm: Revert "Defer persistent reservations until after paging_init()" 8a5b403d71aff arm64, mm, efi: Account for GICv3 LPI tables in static memblock reserve table [Regression Risk] The change in reserved regions only impacts arm64.
