“mmc0: cache flush error -110” during Orin work

[NoahYuan]

Hello, We encountered an issue with eMMC when using the Orin module.
During the normal operation of Orin, the following fault alarm will occur with probability: (captured through Orin Debug UART), When a fault occurs, the CPU’s iowait will be very high, causing the system to be very stuck. At the same time, the system log cannot be recorded in syslog.
Jetpack Version: 5.1.2

Hi,
Here are some suggestions for the common issues:

1. Performance

Please run the below command before benchmarking deep learning use case:

$ sudo nvpmodel -m 0
$ sudo jetson_clocks

2. Installation

Installation guide of deep learning frameworks on Jetson:

• TensorFlow: Installing TensorFlow for Jetson Platform - NVIDIA Docs
• PyTorch: Installing PyTorch for Jetson Platform - NVIDIA Docs
  We also have containers that have frameworks preinstalled:
  Data Science, Machine Learning, AI, HPC Containers | NVIDIA NGC

3. Tutorial

Startup deep learning tutorial:

• Jetson-inference: Hello AI World guide to deploying deep-learning inference networks and deep vision primitives with TensorRT and NVIDIA Jetson
• TensorRT sample: Jetson/L4T/TRT Customized Example - eLinux.org

4. Report issue

If these suggestions don’t help and you want to report an issue to us, please attach the model, command/step, and the customized app (if any) with us to reproduce locally.

Thanks!

please test with jetpack5.1.4 too. This error seems from IOMMU.
