We observed “Synchronous Exception at 0x000000026D83DA64” at UEFI when boot. The issue is seen if connecting one of the USB Type A port at the Orin Nano to the upstream USB-C port at a docking monitor such as Dell U2722DE or a Lenovo Docking station via a USB Type-A to USB Type-C cable. If we don’t connect to a docking monitor or docking station, then we didn’t see this issue.
Jetson System firmware version: 36.4.3-gcid-38968081

How do we fix it?
