Bingo!  I used to commute every day by train, working on my linux laptop 
as I traveled.  What I soon discovered was that when wireless connects 
in an area with a weak and intermittent signal, and then it looses the 
connection, that as the connection is lost, it would hang the laptop, 
including the looping sound and power-off reboot.  Only thing is, that 
laptop was running Mandriva. This would have been about 2005-2006 
time-frame. I used to have to flip the switch that shuts off the 
wireless to get anything done.  Then, after a new release, the problem 
completely disappeared, Mandriva fixed it. Now that I'm running ubuntu 
on a new laptop (Mandriva didn't like the hardware), the problem is 
BACK! Mandriva was able to completely fix it with a new release, 
something different in the wireless stack.  I wish ubuntu would do the same!
