New Auto reboot issue after two hours of screen lock

[rednotec]

I am reporting a persistent issue encountered on my Xiaomi 15 device after installing EU ROM.

Issue Description:
The device functions normally during active use (screen on) and short periods of screen lock.
However, if the screen remains locked for two hours, the device will automatically reboot.

After rebooting, the device successfully enters the system and functions normally again, if the screen is locked for another two hours, the device will reboot once more.

Seems like some problem related to storage (vold/volume daemon), but there's nothing informative about it in the log.

what should I do next?
would it help to collect more detailed logs or provide specific device/storage details? Let me know how I can assist further.

No clue. Never seen an issue like that, and nothing like that was reported. Doesn't look like an issue we are equipped to debug, not to mention fix without source code.
