As far as I can tell the environment is not important here.

>Description:
The machine panics when you exectute the following command:

	dd if=/dev/mem of=/dev/null bs=10k count=1000

>How-To-Repeat:

	dd if=/dev/mem of=/dev/null bs=10k count=1000

>Fix:

	I don't have a panic dump at this point since I was in X when 
this happened. I will try to get one tomorrow, but I figured Jordan 
wanted to get this into his known-problems list.
