So doens't look like probe being slow is the issue here. I suspect the problem is these guys: [ 18.297317] [drm:drm_dp_dpcd_write_payload.isra.11 [drm_kms_helper]] status not set after read payload table status 0 So the display itself is maybe in some wonky state after the BIOS manhandled it. After the replug (at ~67 seconds) the display responds correctly to our gentle prodding and that error is no longer visible. I think this may be due to the BIOS doing something odd, or it may have something to do with the fact that we don't have readout code for MST so we may not be shutting things down properly when taking over.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
