I change first point in the pulldown max from -2.22838e+00 to 2.2838e+00 and
the errors went away. This removed a non-monotonic issue in the curve. It
looks like a bug in the older version. The load line should be intersecting
the pulldown curve in the active region, not in the clamp region.
The -6.58V message is the part that concerned me.
First few lines of the modidifed pulldown table:

Subject: [IBIS] DC and AC data mismatch error in IBIS
Hello All,
I am getting end point errors while running the IBISCHK 3.2.8 parser but no
end point warning or error if I check it with the 3.2.9. I am trying to find
out if this was a bug in the older version or is this something I need to
worry about.
Regards
