If these two things were added I would definitely get another one would be: - a transceiver / SFP+ port with onboard wiring supporting 10gbe and/or 25gbe. (10gbe ports are too big / expensive / hot for them to work cheaply on a board like this.) - A dedicated lane for the m2 SSD, or replace it with a dedicated 4x nvme slot. The machine works just fine as is otherwise, especially with the new 2.5gbe fixes. (It bodes well for the remainder of the unfixed issued. :)) (Having two would mean I could mirror the enclosure to an offsite location, though that's be pricey for the drives as I loaded mine with 4 10TB reds zzz)

Alrighty, thank you. I've been meaning to learn Ansible, so I'll give that a shot.

My plan is as follows: - Insert SD card. - Make a clone / back-up of boot and system using armbian-config whenever I'm about to do something major. (boot and system are both on eMMC) - "unclick" SD card and leave it in the back. - (repeat, until something breaks, and then just insert it and restore using armbian-config if something goes wrong.) I am confused by the eMMC to SD card path though.

fwiw I've stopped using the 2.5gbe interface until this disconnection issue is resolved.

No amount of rebooting is resolving this issue for me.

After upgrade to Armbian 20.11.3 Buster with Linux 5.9.14-rockchip64 eth1 has vanished. ❯ sudo ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether 64:62:66:d0:06:18 brd ff:ff:ff:ff:ff:ff Any ideas? http://ix.io/2I2U

sudo apt-get update && sudo apt-get dist-upgrade -y This will upgrade your unit. I rebooted after doing this, but I'm not sure that you need to.

Ah, thank you.

JohnnyMnemonic you can either wait 24 hours now that you have a like, or you can join the irc channel and ask to be activated.

http://ix.io/2FHd This is the machine in the broken state. (Requiring reboot)

I see! Yes, modifying settings on the windows machine has improved both. However, I am still seeing consistent lock-up / crashing of the interface. Is there anything I can grab for you for details?

Receiving on helios is very slow, sending is slightly faster. Note that rx is on. ❯ sudo ethtool -k eth1 | grep rx-checksum rx-checksumming: on (same with windows, IP Offloading is set to rx only)

Have you tried checking your router's dhcp for a lease on the helios64? If you have the ethernet plugged in when starting it up, and it makes it through sdcard boot, regardless of your serial console it should get a lease. (Then you can SSH in with the same credentials.) I also had no console output when I first tried to set it up, and ended up using the router to discover what the IP was. Make sure you are using the correct COM address. I had to install the driver, and I was on COM4.
