+or not when kexec-tools is updated or a new kernel is installed. The default
+crashkernel values are different for different architectures and also take the
+following factors into consideration,
+	- AMD Secure Memory Encryption (SME) and Secure Encrypted Virtualization (SEV)
+	- Mellanox 5th generation network driver
+	- aarch64 64k kernel
+	- Firmware-assisted dump (FADump)
+
+Since the kernel crasherkernel parameter will be only reset when kexec-tools is
+updated or a new kernel is installed, you need to call "kdumpctl
+reset-crashkernel [--kernel=path_to_kernel]" if you want to use the default
+value set after having enabled features like SME/SEV for a specific kernel. And
+you should also reboot the system for the new crashkernel value to take effect.
+Also see kdumpctl(8).
