Looks like a possible hardware failure of the stacking port.
Contact Dell suport and ask them to check it.

I would also reseat the stacking cables maybe even swap them around and if we see another reboot with the same errors we know it'snot the cables. I would also check the firwmare, I would verify that the switch is running version 3.3.1.10.
