when i built a new kernel based on the latest git tree, i once again
got the black screen of death on my gateway laptop with an integrated
intel graphics controller.
and as i did not that long ago, i got around it by applying the
following tweak to the source tree before rebuilding:
diff --git a/drivers/gpu/drm/i915/intel_opregion.c b/drivers/gpu/drm/i915/intel_opregion.c
index d2c7104..a1a5d03 100644
--- a/drivers/gpu/drm/i915/intel_opregion.c
+++ b/drivers/gpu/drm/i915/intel_opregion.c
@@ -152,6 +152,8 @@ static u32 asle_set_backlight(struct drm_device
*dev, u32 bclp)
struct opregion_asle *asle = dev_priv->opregion.asle;
u32 max;
+return ASLE_BACKLIGHT_FAILED; // rday
+
if (!(bclp & ASLE_BCLP_VALID))
return ASLE_BACKLIGHT_FAILED;
so if this issue was resolved, it seems to have regressed.
