A work-around for the networking problem can be found here. I did this and now I get a short message saying the bootup will continue without full network configuration. This is fine by me, since it seems to make no difference whatever to the behaviour of the laptop.
There is another solution at this URL. I haven't tried that one and, since the work-around seems to work, I probably won't bother.
Never-the-less it is somewhat unsatisfying to have these solutions which say: "do this... edit that... and it will all workout." It would be really nice if somebody would expain what is really going on. Like, what is this "PLYMOUTH" thing? What does it do for networking? Does anybody know where I can find out?
For the sake of completeness, my /etc/network/interfaces file looks like this:
Code:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
iface ppp0 inet ppp
provider ppp0
auto ppp0
Since that second solution recommends changing "eth0," I trien the command "ifconfig -a" to see if there wa anything amiss. here's what I got:
Code:

Doesn't really help, so I'm sticking with the work-around.
