Nano 2GB ttyTHS1 unreliable above 460800 baud

I have seen various conversations around this but I have not been able to dig up a solution yet.

I am trying to connect to the UART on J41 at 921600 baud, but am unable to get clean data.

I am connecting from an Ubuntu laptop with an FTDI adapter.

460800 baud and below work with no issue.

I have been able to run 921600 when connecting to another FTDI adapter on one of the Jetson USB ports.

I have tried different serial terminals and other test code aside from our own code and still have the issue.

Any help would be greatly appreciated!
