If so, kdump serves no useful purpose, and ends up confusing the situation due to its inability to handle 32-bit ELF coredump files. It seems to me that the presence of /proc/vmcore obsoletes the kdump tool. -- Russell King _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
