You can call panic notifiers and kmsg dumpers before kdump by specifying "crash_kexec_post_notifiers" as a boot parameter. However, it doesn't make sense if kdump is not available. In that case, disable "crash_kexec_post_notifiers" boot parameter so that you can't change the value of the parameter.Nacked-by: "Eric W. Biederman" [off-list ref]I think it would make sense if he just replaced "kdump" with "kexec".
It would be less insane, however it still makes no sense as without kexec on panic support crash_kexec is a noop. So the value of the seeting makes no difference. Eric
