Hello,
We have a custom board based on i.MX8MPlus. Up to now we have been working with a Debian11 based FS and kernel 5.4.70-2.3.2 downloaded from NXP. I have also generated SDK following NXP instructions.
Now we have to move to kernel version 5.10.72.
Following the same steps than before I have generated SDK using hardknott release, then download kernel version 5.10.72 and do the porting to our custom board.
But when I try to start the system it hangs, and every 60-65 seconds I can see these traces:

Please, could anyone help with this issue?
Best regards and thank you
