Re: I didn't think you could crash Linux like that!

Adam,

I had the same problem. In my case, it seemed to have something to do with 
hanging Gnopernicus. I use brltty, which operates through a serial port, 
but brltty was stopped also, so I couldn't use the keys on my braille 
display to change consoles or anything. Ultimately I had to press the 
reset button.

That X server is pretty powerful if it can hang Linux. I thought the 
kernel forbade any process from doing this. Some work is needed somewhere!
