I believe those LEDs blink when the kernel panics. If you are not
running X at the time you should see the panic on the screen, otherwise
it can be tricky to get unless you have a serial console or some other
way to dump the console messages when the system dies.
I'd like to learn a reason for this kernel panic but I'm using X and
cannot afford waiting in the text console for hours in hope to get
this kernel panic. Moreover, it may be crucial for kernel panic to
have X running.
Why kernel in the case of panic cannot simply switch the screen to the
text mode and print out a message there?
