[okl4-developer] ARM versatile platform

[Lukas HANEL]

Hi,

please note, that the same tests are hanging on the hardware platform,
too. So it might be a problem with the cpu support.

Is this something I should be worried about?
Should I disable these malfunctioning features, like cache and
inheritance scheduling?
If so, how?

Kind regards,
Lukas Hänel
