So it's intend to be that. I'm still confused with the KMSG_DUMP_KEXEC. crash_kexec() kmsg_dump(KMSG_DUMP_KEXEC) kmsg_dump(KMSG_DUMP_PANIC) Looks like it's equal to original logic, isn't it? kmsg_dump(anything); crash_kexec() So why intruduce KMSG_DUMP_KEXEC? why not just kmsg_dump before crash_kexec? thoughts? -- Thanks Dave
