If you've got a serial port[1], you could also set up serial |
| 13 |
logging. Though using serial ports have become a bit of a lost art, |
| 14 |
the serial console code in the kernel is pretty carefully designed to |
| 15 |
be the last man standing when things start to die. It's possible |
| 16 |
(though I wouldn't say probable) that a serial console will be able to |
| 17 |
show you stuff closer to the event horizon than a network console can. |

Anyway, since still I'm in the serial port business (yes, there are |
| 20 |
still plenty of people using serial ports in industrial settings) I |
| 21 |
had to mention it... |

[1] For this purpose you want a plain old UART on the motherboard type |
| 24 |
seial port. You'd be surprised how many motherboards still have |
| 25 |
them. Even though they're never brought out to a DB9 connector on |
| 26 |
the back panel, there's often an 8-pin header on the edge of the |
| 27 |
board somewhere, so you'd need one of these: |
