Update: this issue appears to be resolved. I've been running kernel 7.1.8+deb13-amd64 for 4 days now, including extended/heavy workload sessions, and shutdown completes cleanly every time — no more hang at session-2.scope/stop, no forced power-off needed.
The fix landed somewhere between 7.1.3 (where I first reported this) and 7.1.8. Same hardware (Clevo V560EU). Closing this as fixed from my side; feel free to close the bug if no one else has reported similar issues on 7.1.3-7.1.7. Thanks for the fix!
