Thanks, Pete, I assume that you have a discrete Radeon card with the Kaby Lake system, can you share details of the discrete and on-board graphics?

FWIW I'm glancing at <https://en.wikipedia.org/wiki/Kaby_Lake>; but it's entirely new to me.

====

For me right now the working combination (sleep and wake entirely reliable, touch wood) for an HP EliteBook 8570p with AMD 'Thames' Radeon HD 7570M is:

r339186

poudriere jail at r339212

drm-next-kmod 4.11.g20180822 poudriere

drm-next NOT installed

# hw.acpi.reset_video=1 NOT set (commented out)

UEFI without CSM.

----

A few minutes ago I edited
/boot/loader.conf to allow hw.acpi.reset_video=1 then installed
drm-kmod g20180930 from poudriere, I'll now reboot. Feedback later.
