Subjectserial (PPP) stomping on parport?
Hi,

I'm having a very unusual problem (well, at least usual to me).  Whenever I
use PPP, I'm unable to print.  As soon as I kill PPP, everything is happy.
It is reproducible everytime for me.  I don't think I'm having any IRQ 
conflicts, I'm not quite certain with the validity of my port number 
assignments.   Right now I'm using linux-2.1.104pre1 (downloading 2.1.105,
see if I have the same problem with that), with glibc 2.0.7pre3.  Any
suggestions?


Here's some more of the system information:
