Rock64 lost connection after high I/O traffic
#1
Hello Everybody, I´m new here and ask for help in this matter.

I have a Rock64 4G v2 and a tried it with many different Ubuntu bionic and Debian os, as:
-   Armbian_5.69_Rock64_Ubuntu_bionic_default_4.4.167
-   Armbian_5.90_Rock64_Ubuntu_bionic_default_4.4.182
-   Armbian_5.98_Rock64_Ubuntu_bionic_default_4.4.192
-   Armbian_5.98_Rock64_Debian_buster_default_4.4.192 (last one).

With all those os I get the same errors after dmesg: pls compare https://pastebin.com/0bxG6RC1

Do you think it is an hardware (memory) problem?

After normal boot and a while it get stuck and lost ssh or Ethernet connections.

I really don´t know what can I do with this SBC. Could yoo please help me?

How are you booting your system. Possibly a bad SD card. Also check out your power supply. Possibly under powered on boot. Also try changing your HDMI cable.

Thank you for reply. The System boots on a NEW flashed 16GB microSD card (SanDisk, A1 class). Before I had a corrupted 32GB microSD card of Samsung Pro Endurance. The power supply is still the EU Original one I've purchased from the Dealer in Germany. I've never used the Rock64 with Monitor and HMDI cable, but only on ssh Terminal.

Try connecting a HDMI monitor to the board and examine the boot screen.
