Guru Meditation Error Dumps

[crankshaft]

I am getting frequent crashes with any code that uses interrupts or threads and thought that I would create a thread recording the crashes that I (and others) encounter so that they can be investigated and hopefully fixed.

@jmarcelino - good point, thanks I have added them.

You should add which board (WiPy, LoPy or SiPy) the dumps come from and precisely which firmware version you're running, otherwise they can't be used for tracing the problem
