Hello again from Gregg C Levine
Right now I am doing a recompile of my kernel, after patching it,
using the patches found in that directory of today's snapshot.
=20
So far, I am working my way through. Only the DoC ones were built as
modules.
More, as I work my way through. This is a new aspect of working with
Linux, so I am quite literally groping in the dark here.
Ladies and Gentlemen: Because I suspect there are others out there,
who have gone through this, I would greatly appreciate a response from
everyone else who has had these problems happen to them before.
