Brand new CB2 V3.0.2 halting on its own after a fresh install

Just received a CB2 to replace my CB1. It is currently paired with a Pi4B Adapter.
Flashed the CB2 3.0.2 firmware without Obico (CB2_Debian12_Klipper_kernel6.1_20250821_without_obico.img.xz) via RKDevTool

All I've done is update the Klipper packages in the Mainsail UI. After a reboot, the CB2 runs fine, from the logs, after ~10min, the system halts on its own. It seems that 16:36:34 is the timestamp where the issue begins.

Start with the supplied journalctl output around 16:36–16:40, then inspect fstrim.service and the KlipperScreen service logs to determine whether the system halts or only KlipperScreen restarts. Compare the fresh CB2 Debian 12 firmware setup with the post-update state; done means identifying a reproducible cause and a verified way to keep the device running.
