The ones I really hated where when they turned out to be a problem with
the hardware.

annoying.

Most of the time it's fine, well with old style PCB where you could actually do things like probe chips, but I did have an interesting one where the RTC just wasn't counting. So I looked at the code to make sure it was initialised correctly and all seemed fine. So next up look at the hardware signals to see if anything didn't seem right. So out with oscilloscope and circuit diagram and that's when I got confused. Probing the chip meant that it then started working. That's when you go and get one of the hardware guys to help you out. Turns out it was just that the oscillator circuit wasn't quite right and probing it, kicked it into life.
I also had one where going into transmit caused the transceiver to reboot itself. That turned out to be a naff power cable where the RF was interfering with it.
