What AUCTeX version does this relate to?  11.55?

You have the handbrake on.

I cannot reproduce it with these file contents

\documentclass{article}
\begin{document}
  \begin{subequations}
  \label{EuMaclau}
  \begin{align}
  % \label{}
  \sum_{\nu=M}^{N} \, g (\nu) & \; = \; \int_{M}^{N} \, g (x) \,
  \mathrm{d} x \, + \, \frac{1}{2} \,
  \bigl[g (M) + g (N)\bigr] \notag \\
  & \qquad + \, \sum_{j=1}^{k} \, \frac {B_{2j}} {(2j)!}  \left[
    g^{(2j-1)} (N) - g^{(2j-1)} (M) \right] \, + \, R_k (g) \, ,
  \\
  % \label{}
  R_k (g) & \; = \; - \, \frac{1}{(2k)!} \, \int_{M}^{N} \, B_{2k}
  \bigl( x - \Ent{x} \bigr) \, g^{(2k)} (x) \, \mathrm{d} x \, .
  \end{align}
  \end{subequations}
\end{document}

and point at the start of the line with "\begin{subequations}" before
typing `C-c C-q C-e'.  There is no hang and the result looks alright.

This is with

Emacs  : XEmacs 21.5  (beta22) "cucumber" (+CVS-20051010) [Lucid]
