That last working rev of drm-next on my end is: 390597ec789 I've been going through commits since then trying to figure out what specifically broke but haven't made much progress. there is a thread on freebsd-current@ where another user is running into this issue as well. on my end the following sysctl knob allows me to suspend on rev 390597ec789 hw.acpi.lid_switch_state=S3 as a said tho - this is currently broken on revisions after that commit. while you are in there setting sysctls, another knob i'd suggest setting is this: dev.drm.skip_ddb=1 this will increase the chances of you entering gdb if a panic happens allowing you to dump a core file and assist with debugging should the need arise. cheers, -pete -- Pete Wright pete@nomadlogic.org @nomadlogicLA
