This is quite a common issue on the 7104 and 7103. There has been
discussion of it here in the past, but I don't think anyone ever
tracked down the exact cause and cure.

On one of my 7104s I was able to sort of fix it by putting 1.2K in
parallel with R1922 and 1.1K in parallel with R1925, but I was never
exactly happy with that.
