If "C-x s" worked, so would C-g, perhaps, and perhaps you could have
produced some backtrace to show us where the problem happened.

If C-g doesn't help, then when this happens, attach GDB to Emacs and
produce the C-level backtrace and Lisp-level backtrace (with the
"xbacktrace" command), then post that here.

Without some supporting data or a recipe for reproducing the problem,
I don't see how we can make any progress with the information you
provided.
