This sounds a little wierd.  At my old job I was regularly using the
same external disk box on both a 3100 and a 5100...

This will happen whenever the console driver sees a "break" and then
drops you into the kernel.  Now, it just so happens that moving a cable
at the wrong time can cause a break.

One solution to this is to actually disable entry to ddb from console
with:

	sysctl -w ddb.fromconsole=0

This is unrelated.  If you could copy the exact error message we should
be able to make more sense of it.
