Richard, trying the Armbian image from
https://apt.armbian.com/pool/main/l/linux-4.20.7-sunxi/ I get:
$ arm-softmmu/qemu-system-arm -M orangepi -m 512 -nic user \

I'm trying to reproduce the error you reported here with my patch set on latest master,
but so far without any result. The host OS I'm using is Ubuntu 18.04.3 LTS on x86_64.
I ran several times using the same 4.20.7-sunxi kernel and same command line.
Some questions that might help:
1) Are there any specific steps you did in order to produce this error?
2) Could this be a known / existing issue?
3) How many times did you see this error?
4) Are you also using Ubuntu 18.04.3 LTS on x86_64, or a different host OS?
Regards,
Niek
