Hi Imre ,
Sometimes it has been observed on Gen9 that screens-disabled
i915_pm_lpsp sub-test failed because power well 2 was not disabled when
subtest checks its register value. It get disabled slightly later.

https://intel-gfx-ci.01.org/tree/drm-tip/IGTPW_2866/fi-cfl-8109u/igt@i915_pm_lpsp@screens-disabled.html

I checked it locally and found similar behaviour (there were three
screens connected in my test), below are the log snippet.

[ 254.042328] [IGT] i915_pm_lpsp: starting subtest screens-disabled
[ 254.042374] [drm:drm_mode_setcrtc] [CRTC:47:pipe A]
[ 254.250784] [drm:intel_disable_pipe [i915]] disabling pipe A
[ 254.421970] [drm:drm_mode_setcrtc] Returning [CRTC:47:pipe A]
(kernel instrumenting log to indicate drm_mode_setcrtc has returned)
[ 254.421990] [drm:drm_mode_setcrtc] [CRTC:65:pipe B]
[ 254.423605] [drm:intel_disable_pipe [i915]] disabling pipe B
[ 254.437460] [drm:drm_mode_setcrtc] Returning [CRTC:65:pipe B]
[ 254.437476] [drm:drm_mode_setcrtc] [CRTC:83:pipe C]
[ 254.438526] [drm:intel_disable_pipe [i915]] disabling pipe C
[ 254.456603] [drm:drm_mode_setcrtc] Returning [CRTC:83:pipe C]
[ 254.464966] [drm:intel_power_well_disable [i915]] disabling power well 2

We can see power well 2 is getting disabled after 8ms of
drm_mode_setcrtc() ioctl returned, which is sufficient to fail the test.

Do u see any issue with driver behaviour.

If it is expected behaviour from i915 driver then we may need to have
some wait while checking the power well 2 for lpsp.

Thanks ,
Anshuman Gupta.
