All works well until we attempt to copy /proc/vmcore to some target place ( disk , n/w ). The system immediately resets without any OS messages after having copied few mb's of vmcore file. Problem also occurs with 2.6.27-rc8 and latest kexec-tools. If we pass 'mem=4G' as boot parameter to the first kernel, then kdump succeeds in copying a readable vmcore to /var/crash.
