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
http://soulinfo.com/~hugang/swsusp/x86_64_log/
thanks.
