After extended testing with your DMI patch applied, the hard freeze is
gone. However, with ASPM disabled but LPS Deep still active, I observe
periodic h2c timeouts during idle which cause occasional WiFi
throughput drops and Bluetooth audio stuttering. When I additionally
set disable_lps_deep=Y, all symptoms disappear completely. This
confirms that combining the ASPM quirk with dynamic LPS_DEEP_MODE_NONE
would be the complete fix. Ready to test an updated patch if you
decide to include this.
