No recovery from sleep/suspend mode?

No recovery from sleep/suspend mode? Using the Debian 12 image from the IndieDroid OS web page. I have explicitly disabled the screen server, screen locking, sleep timer, etc. And yet, the system goes into sleep mode and will not recover, keyboard and mouse are ignored. Only way to recover use of device is to remove power and insert power, i.e. boot up from cold start. All networking is lost, so can’t use SSH to try to diagnose the issue, once it happens. This happens when using micro SD card or EMMC module as boot device. Help?

We’ve heard good reports about the Ubuntu images. Maybe this issue is solved in those distros?

Except I need Debian… it is our standard OS.
