Which information can i provide to help > investigating this matter? have you tried suspend/resume without having the drm-next kmod loaded?  I have run into a couple instances of that breaking due to drm-next. if it does work w/o drm-next then it might be worth rebuilding the pkg locally (via "cd /usr/ports/graphics/drm-next-kmod && make package" for example) and see if that fixes it. there is also a sysctl knob i've set in the past to help in this area, i'll dig through my notes and see if i can find it... -pete -- Pete Wright pete@nomadlogic.org @nomadlogicLA
