I am experiencing the exact same Embedded Controller shutdown issue on a ThinkPad T16 Gen 3 (Meteor Lake).I am running Linux Mint 22 (Ubuntu base) using the Kernel 7.0.0-30-generic.Behavior:Upon triggering a regular shutdown, the system blanks the screen and cuts power for 3 seconds, but then the laptop boots itself back up automatically.Important details & Current Workaround:The machine used to run Windows 11 perfectly fine without any shutdown or reboot loops.As a temporary workaround, I mapped the physical power button to Hibernate. Hibernation works correctly and the laptop remains powered off, confirming this is specifically an ACPI S5 shutdown / EC handshake bug under Linux.Please include the ThinkPad T16 Gen 3 in the hardware list for the upcoming EC/Kernel fixes.
