Solved on my end by stopping XHC (bluetooth related) from allowing the macbook to resume.

To solve permanently create a file called '/etc/udev/rules.d/90-xhc_sleep.rules' and put the following in that file:

#----------------------------------------------
# disable wake from S3 on XHC1
SUBSYSTEM=="pci", KERNEL=="0000:00:14.0", ATTR{power/wakeup}="disabled"
#----------------------------------------------

After a reboot the problem has gone away.

The original reporter had this in his dmesg:

> [ 946.610514] thunderbolt 0000:07:00.0: suspend finished
> [ 946.611183] xhci_hcd 0000:00:14.0: System wakeup enabled by ACPI

Meaning that right after the suspend was completed, the machine got woken up by xhci_hcd. I have the same message in my dmesg.

This possibly also solves these similar bugs:
