If so could you test this with a Yes, a single monitor. As I described in the original bug description of this BZ. > direct DP cable going between laptop and monitor without MST hub.

But the issue happens if I connect laptop directly to display. The issue is present with both HP ZR2440w and HP Z27i displays. > Please do this test and let me know what you see and attach the dmesg logs > if you still see the issue. There's a debug dmesg output already attached to this BZ. Isn't that enough? This is trivial to reproduce. Am I the only one experiencing this issue? This is clearly a regression between 3.16 and 3.17. Having this issue on multiple laptops, multiple displays, multiple kernels.</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> </ul> </body> </html>
