Try enable debug in swsusp, 
<....>
#include "power.h"
#undef pr_debug
#define pr_debug printk
<....>

 Enable serial conosole, 
 Adding console=ttyS0 in boot command line.

Then do software suspend, And send the log to me, that will useful. 

For other reference, I using qemu As X86-64 emulation, But current qemu
X86-64 not full works, the kernel hang after copy_page in suspend, I'll
enable CPU and ASM log in qemu to finger other where is the problem.
