Networking issue with TX1+Orbitty

Robotics & Edge Computing Jetson & Embedded Systems Jetson TX1

Hello,

we are using Orbitty-Boards together with TX1 Modules. Several times a day on some boards, networking fails.
The link and the interface (eth0) go down und up again which currently makes the boards unusable in production.
The cause of the USB-Resets on usb 2-2 is also unclear. We have some usb3 streaming device on 2-2…

Sometimes there is a Tx status -2 seconds before carrier off:

2019-03-06T08:25:04.881858+00:00 kernel: r8152 2-1:1.0 eth0: Tx status -2
2019-03-06T08:25:04.888024+00:00 kernel: r8152 2-1:1.0 eth0: Tx status -2
2019-03-06T08:25:04.894368+00:00 kernel: r8152 2-1:1.0 eth0: Tx status -2
2019-03-06T08:25:07.111090+00:00 kernel: r8152 2-1:1.0 eth0: carrier off
2019-03-06T08:25:07.248577+00:00 kernel: r8152 2-1:1.0 eth0: carrier on

When there is some usb-autosuspend enabled, the interface is set to 100MBit after carrier on.
It’s only advertising 10/100 Full and ethtool is unable to change anything about it.
Disabling autosuspend only fixes the autoneg issue but not the carrier off/on issue.

Hi maax,

Please put your module back to devkit and start the test again.
Also, TX1 ethernet is actually using usb interface, so maybe these two error ar e related.

You could enable more log by

echo 0 > /proc/sys/kernel/printk

Please share the error log again after the test on devkit is done.
