Kdump's backup (in kdump terms, it is "Capture Kernel") kernel is with 
minimal set of features and modules (scsi drivers, network drivers etc.) 
to have small memory footprint and resources to just handle crash dump 
related things. So,it's not a full replacement of primary kernel. Also, 
the point is not to make boot when crash occured. The idea is to take 
control when a crash occured by backup kernel without any need to reboot.
