TerrainFlyTess ICL error state (2019-10-09 drm-tip)

Jani extended the ICL loan.


Unfortunately neither drm.debug nor CONFIG_LOCKDEP=y shows anything:
-----------------------------------------------------------------------

won't reprogram it.
[  151.523211] [drm:intel_combo_phy_init [i915]] Combo PHY B already enabled,

[  187.993338] GPU hangs can indicate a bug anywhere in the entire gfx stack,
including userspace.
[  187.993339] Please file a _new_ bug report on bugs.freedesktop.org against
DRI -> DRM/Intel
[  187.993340] drm/i915 developers can then reassign to the right component if
it's not a kernel issue.
[  187.993341] The GPU crash dump is required to analyze GPU hangs, so please
always attach it.

-----------------------------------------------------------------------

No idea whether the worse reproducibility (1/3 instead of 1/1), is due to using
latest git kernel, or debug options.  Attached is new error state.
