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.
