I've been checking out kdump on FC7. There are a couple of kernel config options cause the crash utility some issues.
These are CONFIG_PHYSICAL_ALIGN=4MB and CONFIG_PHYSICAL_START=16MB.
When the values differ on a reclocatable kernel we loose the ability to make line number references to the code addresses (vmlinux will have line numbers relative to START, kallsyms will reflect ALIGN). This wouldn't be the case if ALIGN and START were both 16MB. Is there is advantage in not doing that?
If there isn't can we make a point of building future release kernels with the two values equal?
