SPC-u M-x does not work with helm-M-x, it fails with:
Error: Specifying a prefix arg before calling helm-M-x

This is because helm-M-x takes the universal argument in the normal way (C-u) after invocation: emacs-helm/helm#696

It might be good to add a sentence or two to this section: https://github.com/syl20bnr/spacemacs/blob/master/doc/DOCUMENTATION.md#universal-argument.

Nice catch, there is some inconsistencies with SPC-u as the universal argument, I wonder if I should remove it tell people to use SPC n , and the like.

Maybe that's a good idea. The nice thing about that is that it doesn't break macros.

+1 for documenting this.
This thread just saved me acting stupid while trying to execute C-u M-x org-reload to work around this issue. For the record, it's SPC : org-reload C-u RET in spacemacs.
