Kernel exec functions and new problems (long)

[Gregg C Levine]

Hello again from Gregg C Levine
Well, switching to the latest of Eric's kernel exec tool, has made a
difference. Instead of getting those annoying "oops" messages, I am
now getting something far more meaningful. Although it means nothing
to me, (or it should and I don't know what to look for), it does
indicate, that your assertions Andrew are leaning towards being
correct. Here's the message:

At a guess, I'd say, it is telling me that the function was not
correctly implemented on this kernel, which is 2.4.20. So, this does
backup that notion that I should grab a copy of the raw 2.4.19
sources. I'll do that later today, and try again. However while
building the version 1.8 tool, I received a number of warnings,
nothing severe just simple warnings. I'll post them after the
signature block.

And that's what it said. Now where do I install everything?
