CONFIRMED: WARNING: problem reading state of external interrupt lines.

Hello Robert,

> Something to consider is cracked capacitors.

Thanks for the tip.

Another hypothesis that I want to investigate is whether we may be
operating the LPC2138 under "off spec" conditions. Most chips will
still run (slightly) off spec, but some won't.

This would explain why resoldering all of the pins of the LPC2138 did
not help, but replacing it by another made the spurious interrupts go

It is just a hypothesis.

Kind regards,
