It's a bit worrisome that your regression occurs both on CURRENT and STABLE. There was an update to both drm-next-kmod and drm-stable-kmod last week, but both are very minor. One question, did you install from pkg or compile from ports? Wrt. my own issues, I'm not entirely sure what's going on. I tried a kernel from r333269 and that worked fine, however, r333340 did not. I'll need to bisect exactly which revision causes my regression, with slowness and lag after resume from sleep. Regards -- Niclas
