Funny System crash - quoting from [Bacula-users] mailing list

About twice a year I succeed in crashing Linux, usually by hitting ctl-C

while something is going on with my tape drive.  Well, tonight, I

totally froze my system. Even the little CPU meter stopped working. At

the same time, the CPU was going full out -- I can tell because the

cooling fan starts speeding up.



What is interesting is that I noticed the num-lock and caps-lock lights

blinking in a way that reminded me of something. After a few minutes, I

realized it was sending Morris code.  Now, my Morris code is *really*

rusty, and though I know all the letters, I cannot recognize them very

fast, so I got:



..-.  then waited until the message repeated and got ..-.  .- , then

again (really painful) ..-. .- - and so on.  I finally gave up after

getting:



..-.  .-  -  .-  .-..  .  .-.  .-.  ---  .-. (etc)



For those of you who do not read Morris code:



..-.  .-  -  .-  .-..    .  .-.  .-.  ---  .-.

Linux is funny  :-)
