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.
