While setting up the FDT for kexec, CPU nodes that are added after the system boots and reserved memory ranges are incorporated into the initial_boot_params (base FDT). However, they are not taken into account when determining the additional size needed for the kexec FDT. As a result, kexec fails to load, generating the following error: [1116.774451] Error updating memory reserve map: FDT_ERR_NOSPACE kexec_file_load failed: No such process Therefore, consider the extra size for CPU nodes added post-system boot and reserved memory ranges while preparing the kexec FDT. While adding a new parameter to the setup_new_fdt_ppc64 function, it was noticed that there were a couple of unused parameters, so they were removed.
