Any time. The moment I saw e1000e, it triggered a memory, so I
immediately went looking through my files to see what it was about
and found it in my son's folder. That reminded me that when he had
that problem, I didn't, so it seemed to be dependent on certain
hardware combinations.

Ah, sorry about that. I was hoping it would be something new for you.

That's odd. Is that something that's commonly done? I've never heard
of putting a driver into a kernel.

That's good, though, right?

Interesting.

Thanks. I'll pass that information on to my son, although he's long
since gotten new hardware and doesn't need that driver any more at
the moment.

I'm sorry. I know how frustrating that can be. Hopefully someone else
will chime in here and offer something better.
