My favorite way to capture the output of a dying system is via the serial port. You can tell the kernel to send console output to the serial port, use a null-modem cable to connect the serial port to another computer, and then use kermit or minicom on the second computer to log the console messages. See Documentation/serial-console.txt for more. If the system isn't dying, just look in your logs. -- Ed L Cashin <ecashin@xxxxxxxxxx> -- Kernelnewbies: Help each other learn about the Linux kernel.
