<pre>So I tried to hack around the function, just like
--- a/drivers/gpu/drm/i915/intel_hdmi.c
+++ b/drivers/gpu/drm/i915/intel_hdmi.c
@@ -1921,7 +1921,7 @@ intel_hdmi_detect(struct drm_connector *connector, bool
force)
intel_display_power_get(dev_priv, POWER_DOMAIN_GMBUS);
- if (IS_ICELAKE(dev_priv) &&
+ if (//IS_ICELAKE(dev_priv) &&
!intel_digital_port_connected(encoder))
goto out;
... and this seems working. No NVMe-related errors are seen after this.
I don't mean that this is the right fix, but it indicates that poking the HDMI
detection for HDMI-3 screws up the NVMe on PCIe, apparently.</pre>
