Comment 7 for bug 1920784

As my other repro-code didn't trigger the issue I looked at qemu again and found that before the failing ioctl->scv call there are plenty other even some very similar (same?) calls that work just fine.

I wonder if on guest setup qemu (or e.g. the rom we load) might set some arch-bits or such which then breaks the next "scv 0" call.

I attached the full ioctl log here.
