To be sure, the command line option you are using is "i915.enable_psr=1" right ? And not "intel.psr=1" like you've stated above. Does this happen only if you boot with i915.enable_psr=1? When do you start seeing the flip time outs? login screen? or are you running any tests? What happens if you keep the screen busy? like playing a video or let's say keep moving the cursor?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
