Commit 62b69566 ("drm/i915: Only enable DDI IO power domains after enabling DPLL") changed how the DDI IO power domains get enabled, but neglected the need to enable those domains when enabling a DP connector with MST enabled, leading to Kernel panic - not syncing: Timeout: Not all CPUs entered broadcast exception handler Fixes: 62b69566 ("drm/i915: Only enable DDI IO power domains after enabling DPLL") Cc: Imre Deak <imre.deak@intel.com> Cc: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Cc: David Weinehall <david.weinehall@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: intel-gfx@lists.freedesktop.org Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reported-by:
