When I using Qemu as X86_64 emulataion for testing software suspend, I
get the first oops the instruction is this, 
IN:
0xffffffff80116a8a:  movzwl 0x8(%rbx),%eax
0xffffffff80116a8e:  mov    %eax,%ss	<- general protection 

That's in 
arch/x86_64/kernel/suspend.c +105
 asm volatile ("movw %0, %%ss" :: "r" (ctxt->ss)); <-- general protection.

I don't why, but I check %eax and %ss are same value, so I just comment 
this line, the oops go away, But still geting hang, Now I have no idea,
:)


I put the all logs in this

thanks.
