hm... Base on dmesg, the hibernate subsystem didn't find any hibernate image,
that causes system didn't resume:

[    3.472078] PM: Basic memory bitmaps freed
[    3.474816] PM: Starting manual resume from disk
[    3.474819] PM: Hibernation image partition 8:2 present
[    3.474820] PM: Looking for hibernation image.
[    3.475052] PM: Image not found (code -22)
[    3.475056] PM: Hibernation image not present or could not be loaded.

But, currently I have no idea why the hibernate image didn't find. There have
another doubtful thing is there have ioremap warning when trying to add pci
device:

[    0.267916] ------------[ cut here ]------------
[    0.267921] WARNING: CPU: 0 PID: 1 at arch/x86/mm/ioremap.c:63
__ioremap_check_ram+0xb3/0xc0()
[    0.267922] ioremap on RAM pfn 0x2551

Per kernel source, looks 0x2551000 should be the PG_reserved System RAM and
kernel try to ioremap it. The above message is warning. I am confusing for this
warning message because the pages of setup_data are reserved but why emit
message.
