This happened to me just a few weeks ago. I was monitoring payload comms for a high-altitude research payload that we had built, and all the data comms went through a Linux box that was routing traffic to the payload.
Everything was going smooth as silk in mission control and then... lost connection to the payload from the mission controller station... I go to the linux router, and its LOCKED UP... nothing... screen is frozen with my windows up, no mouse movement...
CAPS and SCROLL led's are blinking in unison... some kind of code... maybe a number? I start trying to write down dots and dashes, but my autonomic response is to try to copy is as morse code... I get characters... then I scrawl out...

Linux was sending me morse code via the keyboard LEDs! That's a new one on me. It didn't send any kind of diagnostic code, not that it would've helped me. But knowing that it was a fatal exception was actually the right information, because I knew it was appropriate to immediately restart the machine.
So instead of the Windows blue screen of death, it's the linux "Morse String of Death" (MSOD?) !

Is Burning Man still relevant?
