Jetson Thor Linux Kernel Segfault after clean install

I just followed the Jetson Thor Quickstart Guide ( Quick Start Guide — Jetson AGX Thor Developer Kit - User Guide ) and it looks like it successfully installed (went through the install screen prompts) but now when it goes to boot and I connect to the debug port (the port under the cover), it shows a kernel panic (full boot log and kernel panic error message attached below) just after it gets to the login prompt.

nvidia-jetson-thor-boot-log.txt (83.4 KB)

Snippet of just the kernel panic:

I did just purchase this unit from Amazon so could this be a hardware problem? Or is this a kernel bug? Thanks!

You could try

sudo apt update && sudo apt upgrade

to upgrade from l4t 38.2.0 to 38.2.2 to see if it helps.
