Public bug reported: On ThinkPad X1 Carbon Gen 9 (20XXS1KS0F), the UCSI PPM (Platform Policy Manager) may permanently deadlock after any EC communication event involving the USB-C/Thunderbolt charging stack. Once deadlocked, charging stops and no further plug/unplug events are detected until the EC is power-cycled (30-second power button hold or emergency reset).
