Hi,

I have same issue (thinkpad T450s) after resume notebook cant wake up 
but on:
  FreeBSD 12.0-CURRENT #0 r332796: Fri Apr 20 00:42:44 UTC 2018 
root at releng3.nyi.freebsd.org:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64

drm-next-kmod-4.11.g20180224
gpu-firmware-kmod-g20180206_1

# sysctl debug.bootverbose=1
# sysctl debug.acpi.suspend_bounce=1
