Very sorry about the timezone issue. We did have an NTP problem. Hopefully
things should be ok now.

No this is a unknown benign issue when using KPTI kernel on Xen (see [1]). I
still haven't found time to fix it and would appreciate help to solve the
issue.
I had a lot of issues getting the R-Car M3 running as a user and only got it
working with Andrii's instructions. I am personally not that familiar with the
internal functionality of KPTI or Xen.
Don't worry, it was more an open question as many people seems to hit the issues
but no-one have found time so far.
Regarding running Xen on R-Car M3, would you mind to update/add the instructions
on the wiki?
If you have any tests you would want to do on my current configuration I will
gladly give it a go.
Thank you for the offer. I will let you know when I managed to reach that in my
list.
Best regards,
