Without knowing more about the content of your code and comment (and
F90's syntax) I'm not sure if column 7 is the right choice for the
indentation of the new line, but it sounds reasonable.

I expect the same happens if you just hit TAB instead of RET, right?

If so, the problem is not directly linked to the electric-indent-mode,
and is instead either a bug in f90-mode's indentation code or maybe it's
controlled by a config var in `f90-mode` (since it sounds to me that
comments in column 1 are an old F77 convention which you may or may not
want to follow in F90 code).

It's probably neither: the indentation rules probably looks at preceding
*code* rather than preceding comments ;-)

There's always some twisted logic behind craziness.
