Anders, are you running the same kvm-unit-tests commit that passed for 
5.2.2?  My suspicion is that your previous test didn't have this commit

    nVMX: Test Host Segment Registers and Descriptor Tables on vmentry of nested guests
    

since the symptoms match and the corresponding fix was made in 5.3.

I think Linaro's tests would be helped by making kvm-unit-tests.git a submodule of
Linux, but I'm a bit wary since it would be the first submodule and I wouldn't know
where to put it...
