To avoid this, please enable the address presenting by: [root@cachyos-x8664 ~]# echo 0 > /proc/sys/kernel/kptr_restrict [root@cachyos-x8664 ~]# cat /proc/kallsyms |less 0000000000000000 A fixed_percpu_data 0000000000000000 A __per_cpu_start 0000000000001000 A cpu_debug_store 0000000000002000 A irq_stack_backing_store ... then invoke the crash for live debug will have no problem. Also if you are dealing with the newest kernel, both makedumpfile and crash will need to be newest, otherwise some bugs you may encounter.
