DSi: Closing the lid will shutdown occasionally

[VariantXYZ]

Using the v0.5.2 release, and having the nds file installed as a system title (via TMFH) and booting it from the system home menu. I am not using TwilightMenu, but I do have hiyaCFW installed.

Closing the lid will always seem to go into 'sleep' mode where the DSi's light will flash, but re-opening it will (most of the time) result in the system being shut off. I saw a similar post on the GBATemp thread from 2013 talking about this issue, but the associated video wasn't available anymore.

Let me know if there's anything else I can test or if you want me to try with a debug build. I've been unable to successfully consistently suspend on multiple DSi consoles with this setup.
