I haven't tried yet. Looking at the thread sofar the problem was noticed on
a system with a Celeron N2930, I don't have access to one of those, I
do have access to a system with a closely related N2840 I will give that
a try as well as see if I can reproduce this on one of the tablet
oriented Z3735x SoCs.
I'll report back when I have had a chance to test this.
Regards,
Hans
