As suspected a DP screen, and we disconnect right before a modeset sequence. The unexpected thing here is that the modeset santizer kicks in and wreaks utter havoc due to a lid event. Now we shouldn't hang the entire box fundamentally when we unplug the DP cable, and that's a bug in the DP code. It's also quite some work. But we also should be a bit less enthusiastic with wreaking havoc in the lid noifier, and I think that can be fixed quickly. I'll reply with some patch. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
