> Reporter, please comment to question raised by DK.

Sorry for the late response! 

> To be sure, the command line option you are using is "i915.enable_psr=1" right ? 

Correct, as you can see in dmesg boot option is "i915.enable_psr=1".

> When do you start seeing the flip time outs? login screen? or are you running any tests?

In my case there is no login screen, because autologin is enabled in Gnome
settings. I run test described in item 2:
https://bugs.freedesktop.org/show_bug.cgi?id=104573#c12

> What happens if you keep the screen busy? like playing a video or let's say keep moving the cursor?

Can't tell for sure, because I wasn't able to use Wayland session long enough
due to issues with Gnome's integrated onscreen keyboard, and lack of other
Wayland-compatible onscreen keyboards. As far I remember issue does not happen,
but maybe because I didn't test long enough.
