Comment(by Quozl):

 Replying to [comment:4 greenfeld]:
 > This is interesting in that it works but contradicts the same fix not
 working for Scratch in #9655.

 Given the symptom is dependent on the switching of power during program
 execution, it is no surprise that a workaround might only work for certain
 programs.  The scheduling pattern for Scratch is likely to be very
 different to the pattern used by other activities.

 But I consider this entirely a hardware issue, so I'm curious as to what
 ''wad'' thinks about the serial numbers in relation to the intended
 earlier fix.  Sam's sample space is quite small.
