Hi, Please refer below to current setup and observations: Using custom board Auvidea X221 with Jetpack 4.6 (rev 3), built custom kernel using Auvidea’s 4.0 firmware, applied binaries, and flashed using SDK Manager. Upgraded after install, and installed nvidia-jetpack. Upped MTU to 9000 on …

Hi All, Thank you for your responses, it appears the fix from here fixes the bug for both the devkit and the Auvidea board - Kernel panic with jumbo frames in L4T 32.5.1 / TX2 4GB Observation is that the initial ethernet connection on boot has a 100% error rate and that it’s necessary to restart t…

Are you able to use devkit to reproduce this issue? If so, please share me the detail steps to reproduce this issue.

Same exact thing happens on the devkit, please refer to the attached log files and connection config. dmesg.log (72.6 KB) ifconfig.log (494 Bytes) ethtool.log (1.3 KB) connection-config.cfg (313 Bytes)

…but I don’t see any kernel panic in your log. If this is a kernel panic and it rebooted, please share the uart log. Also, I notice your jetpack version seems not latest one, please use latest one to check issue.

Thank you for your prompt responses. Please refer to the uart log from the devkit. System runs fine at 1500 MTU, but 9000 causes the crash. The log shows boot, data collection, crash, restart, data collection, crash. The crashes are immediate. Also, we can’t use anything newer than L4T 32.6.1 as t…

Please just share the method/steps to reproduce issue at this moment.

Steps on dev-kit: Flash Jetson with Jetpack 4.6 (rev3) and SDK components. Setup Ubuntu. Update and upgrade. Install Aravis - GitHub - AravisProject/aravis: A vision library for genicam based cameras Setup ethernet port with nmcli and attached config file below. Place in /etc/NetworkManager/syste…

Hi, It is unlikely for us to use your usecase to reproduce issue. Is there any simpler version to reproduce this? We only have devkit here.

I am curious about something: Is this wired ethernet? I ask because it is phrased that it is probably wired, but the kernel failure is for WiFi. If so, then perhaps it is setting MTU for the wrong device.

@WayneWWW I’ve re-tried the patch described here , it works but with heavy data loss. Do you have an ethernet device that supports jumbo packets? You could try connecting that to a devkit and collect data from it to emulate the crash. [image] @linuxdev Yep, wired Ethernet to the camera, please refe…

It seems that the error is similar to Jetson Xavier AGX reboots when downloading docker image
