Hi Adam,
I'm using an eight-core Cortex-A53 processor. The vm is running 64bit Linux. It is recommended to start two or three vms, that will be easier to reproduce this problem.

Interesting. Could you please be a little bit more verbose, e.g. what
type of CPU/SoC you're using and whether you're on 32 or 64bit?
Would I be able to reproduce this?
