What is the process? Have you an example you can post here? It could be a 
mis-config of the mouse port for GPM or X, or maybe something thinks your 
modem is on /dev/ttyS0 ... digital camera app, lego mindstorms, minicom, a 
whole host :) Another possibility is a stale lock file it's finding that 
hasn't been deleted.

Plonk the output of lsof here and we should be able to point out where to 
look to disable the offender.
