Sorry this took me a little bit to reply to. So-it looks like we did indeed fix the i2c timeout issue that I was seeing on your board, so the next suspicious thing in your log seems to be the fact one of your DP ports (DP-7 in particular) appears to think it's being continuously hotplugged: [ 90.996867] nouveau 0000:01:00.0: DRM: unplugged DP-7 [ 91.191704] [drm:drm_add_display_info [drm]] non_desktop set to 0 [ 91.191711] [drm:drm_add_display_info [drm]] HDMI: DVI dual 0, max TMDS clock 300000 kHz [ 91.297638] [drm:drm_dp_dpcd_access [drm_kms_helper]] Too many retries, giving up.

Are they on any laptop docks/standalone MST hubs, do they go through any video adaptors, what models/brands and what kind of connectors do they use, etc. As well, do you think you can grab another log from your system but using: log_buf_len=50M drm.debug=0x116 nouveau.debug=disp=trace (include the full log from your boot if you can and don't trim it, since it's likely going to be a big log) I have a feeling one of your MST devices is doing some weird out-of-spec behavior that we might need to teach nouveau to handle -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
