            Bug ID: 109282
           Summary: Plymouth won't show LUKS key-presses or boot progress
                    when PSR is enabled
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: sebastian4842 at outlook.com

When PSR is disabled everything is fine, but enabled(i915.enable_psr=1) I have
got the following problems:

-The boot animation progress screen isn't shown or just at the end before the
login screen appears.

-Sometimes the password field for LUKS is available and if not there is only a
blank screen. In case it is displayed no key-presses are shown. Typing in the
password blindly does work in both cases.


These issues are reproducible since kernel version 4.18.X.

Current kernel version is: 4.19.13-300.fc29.x86_64
OS: Fedora 29
