Hi,

This is user space program and using in 1st kernel. I really suggest you
should start a gdb to track what's going on when your real /proc/iomem
is different with the debug printing of kexec. Honestly, it won't be too
difficult, I really like this kind of debugging. If happened in kdump
kernel, even in user space tools like makedumpfile, you have to add
debug printing again and again.

Thanks
