I tracked the events that produced such messages.

1/ During boot
[ 54.163231] [drm:i915_getparam] *ERROR* Unknown parameter 6
[ 55.267287] [drm:i915_getparam] *ERROR* Unknown parameter 6

2/ First time you press "Ctrl+Alt+Fx" to switch to VT x (x=2), the screen flickers but it does not switch to the requested VT
[ 413.364710] [drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for disabled pipe 0

3/ Second time you press "Ctrl+Alt+Fx", it switches to the VT x, but write another error :
[ 417.776700] [drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for disabled pipe 0

4/ When I lock the screen, with command "xflock4" (XFCE desktop), it becomes black normally. But an error is written:
[ 781.018880] [drm:i915_getparam] *ERROR* Unknown parameter 6

Hope it helps.
