Regression amdgpu - Plymouth graphics freezes on Framework 16 laptop and panel replay enablement (kernel 6.11.2 > 6.11.3)

After kernel upgrade 6.11.2 > 6.11.3 on a Framework 16 laptop with Arch Linux, the Plymouth 'scroller icon/graphics' freezes on boot and the passphrase input field is not visible.

Blindly entering the passphrase makes the laptop continue booting after which it seems to operate as usual.

After analysis in issue #3344 (closed) the following observations have been noticed.

  • Rollback of kernel 6.11.3 > 6.11.2 makes Plymouth work again.
  • Suspected cause is the enablement of AMD panel replay in kernel 6.11.3.
  • Applying the 3 panel replay patches on top of 6.11.2 makes Plymouth freeze again.
