Issue fixed with Armbian (19.11.3) and kernel upgrade to 5.3.11.

Hello, I am using up to date Armbian - Debian Buster with Armbian Linux 4.19.69-meson64 Linux version 4.19.69-meson64 (root@builder) (gcc version 7.4.1 20181213 [linaro-7.4-2019.02 revision 56ec6f6b99cc167ff0c2f8e1a2eed33b1edc85d4] (Linaro GCC 7.4-2019.02)) #5.95 SMP PREEMPT Mon Sep 2 01:21:39 CEST 2019. I have encountered Ethernet interface lockup on medium traffic (after 30s-120s when copying big files from external usb disk by sshfs - 240Mb/s). At high/medium Ethernet traffic the issue always occurs. It is most likely caused by some kernel update because I didn't have such problem before.

But system working normally after that. I've never had such warning before (with previous kernel - 4.19.20). Maybe it has something to do with the last Armbian kernel update?

This happened only once. I can't reproduce this bug since then. I have seen that raspberry had similar problems(long time ago): https://www.raspberrypi.org/forums/viewtopic.php?t=49840

Hello, I using up to date Armbian Stretch with kernel 4.19.41-meson64 #5.85 SMP PREEMPT Wed May 8 12:40:37 CEST 2019 aarch64 GNU/Linux. I started using TP-Link TL-WN722N V1 USB WiFi dongle recently. Unfortunately Armbian has crashed and rebooted once during I using such USB dongle. I tried to reproduce this bug once more but I can't. I have installed firmware-atheros package for this USB dongle. Should I install armbian-firmware-full package instead of firmware-atheros? It could help? Log:

Why is that?

I found easy workaround. Add usbcore.autosuspend=-1 as kernel parameter by /boot/armbianEnv.txt file. Eg.: extraargs=usbcore.autosuspend=-1 Of course this workaround have cons: odroid c2 will take more power. @TonyMac32 Could you please give me more details where I should look for this issue in source files? Is it dwc2 usb driver?

Hello, I have installed Armbian Debian Stretch Next (mainline kernel) on my Odroid C2 and updated to newest version(apt update & apt upgrade). Everything works fine except USB ports. I have USB LTE modem which is not recognized. I have tried "lsusb -v" but with this modem not works. But when I connect USB keyboard first then "lsusb -v" and next I connect LTE modem and type "lsusb -v" then it's works. I also tried connecting USB LTE modem before Odroid C2 boot but this workaround not working. Is there any workaround which not involving connecting more than one USB device? Maybe usb kernel modules (usbcore, ehci_hcd, ...) compiled as external modules will help find workaround?
