ArriaV reset fails

May be somebiody knows ti and can help me. I am trying to run linux socfpga-4.14.130-ltsi_20.02.02_pr on ArriaV based board. Every time the kernek has a problem it tryes to reboot the system. It just hangs there. If I enter reboot command - the same, the system hangs and power cycle needed.
Is there a problem with reset in ArriaV or I just didn’t configure something correctly?
