Hi,

I am experiencing the same issue on a PC Engines APU2 running kernel
4.14.34, both with and without hardware encryption. With hw.
encryption, the crash occurs within 2-4 hours. Without hw. encryption,
it takes 7-8 hours. My setup is nothing crazy, between 7 and 20
tunnels with heavy RX/TX.

Has any progress been made here? I would like to try a bisect myself,
but my board is running OpenWRT, which makes bisecting hard. The only
observation I have so far, is that I did not see the issue with kernel
4.9.

BR,
Kristian
