I don't know what you mean by a dead kernel here. If, say, the e1000e device driver is crashy, irrespective of what you use (netconsole or syslog), there's not much help. In this case, you'll then have to resort to serial console. > But why I need to integrate it with initrd? Because it fills the gap in between "kernel load" to "real init start". Imagine a scenario where as soon as the disk driver is loaded, the kernel panics. How would you debug that ? PS: It is just a suggestion. Your patch is still valid, just not very relevant to the use cases. -- Ritesh Raj Sarraf | http://people.debian.org/~rrs Debian - The Universal Operating System
