After connecting the display, frequent freezing occurs after restarting

We mounted the AGX Thor module on our self-developed carrier board. After powering on the system, clicking the restart button on the display interface to reboot resulted in a freeze (such as a black screen or no response) about 3 out of 5 times.

The system version is as follows

nvidia@nvidia:~$ uname -r
6.8.12-rt-tegra
nvidia@nvidia:~$ uname -a
Linux nvidia 6.8.12-rt-tegra #1 SMP Mon Feb 2 11:32:24 CST 2026 aarch64 aarch64 aarch64 GNU/Linux
nvidia@nvidia:~$ cat /etc/nv_tegra_release

R38 (release), REVISION: 4.0, GCID: 43443517, BOARD: generic, EABI: aarch64, DATE: Wed Dec 31 00:15:19 UTC 2025

KERNEL_VARIANT: oot

TARGET_USERSPACE_LIB_DIR=nvidia
TARGET_USERSPACE_LIB_DIR_PATH=usr/lib/aarch64-linux-gnu/nvidia
INSTALL_TYPE=openrm

The log is as follows

The first time I pressed the restart button and entered the password, the screen went white. Three minutes later, the system restarted and entered the system.

When the screen is not connected, log in to the device via SSH, then use the command sudo reboot. I tried it a dozen times, and it didn’t appear.

Is there any way to solve this problem?

This issue will affect the usage of the equipment by the customers.

Will this issue happen if you are not using RT kernel?

Just want to confirm is related to RT.

Standard version: Connect the screen, and after turning on the device, click the restart button on the interface to reboot. After trying more than 20 times, it was able to start up normally each time. …
