One of our purposes, notifying "I'm dying", would be achieved by purgatory code provided by kexec command as I stated before. Since the way of the notification will differ from each vendor, I think we need to modify the purgatory codes pluggable. Also, I think we need some parameter passing mechanism to the purgatory code. For example, passing the panic message via boot parameter to save it to SEL. Although I'm not sure we can do that (I've not investigated well yet). Is that acceptable? Regards, Kawai
