Ard, Mikulas,

After some self-caused setup issues I was able to run the test on my
MacchiatoBin with the kernel v4.18-rc8. It's been running for 1h+ now,
loading the CPU to 100% and no single error event...

I built the binary file with:
gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc -O2

Maybe it's the older firmware issue?

I have downloaded and built the firmware recently (it has timestamp Jul 30
2018).

Do you still have your firmware file "flash-image.bin" that you used, so
that I could try it?

Attached. Please let know if you see any difference.

I booted this image, but the same corruption happens.
