No it doesn't crash until there's a massive and constant amount of traffic going over the WiFi link. Small/sporadic traffic does not trigger the problem. It's not a power issue - the power supply is regulated, and I've measured it under load so I know it holds a steady 5V. I suppose there's a small chance the problem is with one of the voltage regulators on the Pine board...

In case you really want to nail the problem down you could use any Debian variant, then install RPi-Monitor (to see thermal effects) and then fire up 'stress -c 3 -m 3'.
Of course I know the voltage. It's a regulated 5V supply feeding the Pine via the USB connector, and I know it's stable because I've measured it under load. Maybe it's one of the regulators on the Pine board being the problem?
