Just for note:
Found this thread with same bug on Mint 18 on Alienware 13 R2:

Suspend and resume working on Solus LiveCD with kernel 4.8.15.

Different (related to ACPI and PCI) startup messages in journal on Solus:
  kernel: ACPI: Core revision 20160422
  kernel: PCI: Using configuration type 1 for base access
  kernel: ACPI: Enabled 7 GPEs in block 00 to 7F
  kernel: ACPI : EC: EC stopped
  kernel: ACPI : EC: GPE = 0x14, I/O: command/status = 0x66, data = 0x62
  kernel: ACPI : EC: EC started

Different startup messages on journal on Fedora 25 with kernel 
4.9.7-201.fc25.x86_64:
  kernel: ACPI: Core revision 20160831
  kernel: acpiphp: ACPI Hot Plug PCI Controller Driver version: 0.5
  kernel: PCI: MMCONFIG for domain 0000 [bus 00-ff] at [mem 
0xe0000000-0xefffffff] (base 0xe0000000)
  kernel: PCI: MMCONFIG at [mem 0xe0000000-0xefffffff] reserved in E820
  kernel: PCI: Using configuration type 1 for base access
  kernel: ACPI: \_SB_.PCI0.LPCB.EC0_: Used as first EC
  kernel: ACPI: \_SB_.PCI0.LPCB.EC0_: GPE=0x14, EC_CMD/EC_SC=0x66, EC_DATA=0x62
  kernel: ACPI: \_SB_.PCI0.LPCB.EC0_: Used as boot DSDT EC to handle 
transactions
  kernel: acpiphp: Slot [1] registered
  kernel: ACPI: Enabled 7 GPEs in block 00 to 7F
  kernel: ACPI : EC: event unblocked
  kernel: ACPI: \_SB_.PCI0.LPCB.EC0_: GPE=0x14, EC_CMD/EC_SC=0x66, EC_DATA=0x62
  kernel: ACPI: \_SB_.PCI0.LPCB.EC0_: Used as boot DSDT EC to handle 
transactions and events

So, old kernel has older ACPI revision. Don't know what the rest of the
messages mean. But Solus using only pciehp module (PCI Express Hot Plug
Controller Driver). New kernel using pciehp module AND acpiphp (ACPI PCI
Hot Plug Controller Driver). Something about pci hotplug and something
about pci hotplug. And we have bug with pci hotplug.

AND NOW THE GREAT NEWS

Disabling acpiphp with "acpiphp.disable=1" kernel boot parameter solves
our problem. Now I can suspend and I can resume.

Don't know what this workaround will break.

Also I think this is upstream bug. Can anyone report it? Because I'm too
shy.
