The suggestion I have is, as usual when nothing is said about the setup,
try to reproduce the problem without your init file, i.e., starting from
`emacs -Q'.  If you can repro it that way then report the recipe here,
asking for possible suggestions.  Or if you think it is a bug, report it
via `M-x report-emacs-bug'.

If the problem does not occur when you start from `emacs -Q', then try to
narrow down your init file, to see what causes the problem.  Then post
what you find here, if it's not obvious at that point how to fix it.

You say that most of the time repeated C-g works, but sometimes it does
not.  Sounds like Emacs is in an infinite loop.  For that too, I would
first suspect code (loaded) from your init file.  (Infinite loops in
vanilla Emacs get reported and fixed very quickly.)

IOW, a recipe please, or at least some more, and more concrete, info.
