However PSR is triggering this bug somehow. I noticed the following things (about problem with VGA monitor): 1. Problem with VGA monitor completely disappears with i915.enable_psr=2 (and 0, of course, but remains with 1 and 3). 2. VGA monitor flickers only when I'm using two monitors (laptop monitor and VGA monitor). When I use VGA monitor as a single monitor problem not is not happening. 3. Problem starts immediately after I switch link_power_management_policy to min_power and immediately disappears when I switch it back. 4. fifo_underrun messages showing during connection of second monitor only when bug is happening.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
