I don't recall any fixes between v4.18 and drm-tip that would address this. It might prove useful to attach the dmesg. But based on the snippets you've included so far it looks like you have a type 1 dual mode adaptor, and we limit it to 165 MHz. IIUC whether clocks higher than 165 MHz work on type 1 adapters is pure luck, and depend on the electrical characteristics of the adapter and the cable. Since they were designed with max 165 MHz in mind, all bets are off.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
