I have a couple of Nanopi Neo Air. For quite some time they have been locking up, hard lock, LEDs on solid, but I have been unable to find any reason. They're both running Leap 15.2. The lock-ups happened sufficiently frequently for me to start thinking about a hardware watchdog even.

For some reason, last week I decided to disable IPV6 on both of them, just a random impulse/thought. Now, one has 7 days uptime, the other 5 days, looking good.

Just for balance - a third Nano Pi has IPv6 and has been up for 23 days. -- Per Jessen, Zürich (5.6°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland.

I have only standard Raspi 3 and 4, and they are running either Tumbleweed or MicroOS. IPv6 is standard in my home network and the main protocol, no problems at all.
