Yes, known symptoms -- following ONE LINE change
does hide the bug by returning the AIC configuration
into previous model, however it does not really FIX
things :-( (Line numbers may have some fudge on
them, I did add/remove a lot of printk()s to find this.)
(There are two similar changes, however only this one
is apparently necessary!)
