  [amdgpu] Screen fails to wake up after sleep using 5.4.0-66, but

Bug description:
  It looks an awful lot like this issue :
  https://gitlab.freedesktop.org/drm/amd/-/issues/1427.

  I'm hitting these:
  [11596.268677] [drm:dce112_get_pix_clk_dividers [amdgpu]] *ERROR* 
dce112_get_pix_clk_dividers: Invalid parameters!!
  [11596.269781] [drm:dm_restore_drm_connector_state [amdgpu]] *ERROR* 
Restoring old state failed with -22

  Switching to tty2 wakes it up and allows me to switch back and recover
  my xorg session.

  Should this be filed against the kernel, xorg, or amd drivers? I'm not
  sure..
