Description of problem: Plymouth visual stall during boot and LUKS passphrase entry. Version-Release number of selected component (if applicable): My system is a Ryzen AI 9 HX 370 CPU providing integrated graphics, and an Nvidia RTX 5070 Ti, an asus zephyrus g14 laptop. How reproducible: Always on my setup. Steps to Reproduce: 1. Boot the computer 2. 3. Actual results: The luks passpharse entry screen is shown, but no keypresses are echoed, but if I enter the password blindly, the boot continues. The screen refreshes only at the GDM login screen. Expected results: The keypresses are echoed back to the screen. Additional info: First I suspected some timing issue between the dGPU and the iGPU, and tried to disable the dGPU entirely using udev blacklisting, but the bug stayed.

Hello Gergely, Could you please check the suggestion in comment https://bugzilla.redhat.com/show_bug.cgi?id=2455924#c13 regarding the missing LUKS display? If that doesn't help, do you have any other experimental steps in mind to help us diagnose the blank screen during the password prompt? Thanks for your help!
Hi! I replied to that issue.
Adding my result from the issue https://bugzilla.redhat.com/show_bug.cgi?id=2455924 to here, if it turns out to be an other issue: As disabling simpledrvm with "initcall_blacklist=sysfb_init" didn't help, I went on with disabling Panel Self Refresh features by adding "amdgpu.dcdebugmask=0x10" to the kernel boot parameters and this solved the issue completely (AI suggested these, I don't really know what these features are).
As this seems to be a kernel issue, re-assigning.
Found an other similar PSR issue at https://gitlab.freedesktop.org/drm/amd/-/work_items/4264, commented there about this.
