No, this affects both ES45 (with 3 cpus) and XP1000 (one cpu).
The problem is rare. I often have to run tests for 12 hours on
the XP1000 before I see a problem. On miata it might occur even
less often.
I hope I am getting close to the bad commit, but it is taking
time when I run testing for a whole day before I feel confident
enough to mark the kernel as good. And I have been wrong on
that one a couple of times now, having to repeat part of the
bisection.
Cheers,
Michael.
