PWRON_KEY problem with Radxa CM3 IO Board

Hello community,

I didn’t find the category for this post so I’m putting it uncategorized,

We bought a pair of CM3-IO Board units and another pair of Rock-3A units.

For both units we loaded the operating system from release 2020126-1316 and tested the Debian / Ubuntu versions.

The CM3-IO Board is accessed through the U30 Header and the Rock-3A has a push button near the simCard holder.

The problem I have with the CM3 IO Board is that when you power off the unit using the PWRON_KEY the unit turns off normally but when you turn it on with the same pin the unit tries to load the kernel but restarts and stays in an infinite loop. we did debugging through the console but we do not see anything strange, I attach the debug with a successful start off and on where it is loading the kernel.

Any ideas? I tried to load several images with previous releases but they have the same behavior, could it be software or hardware ?
