I didn't know one could have the git repo only for one subversion
(though I find it very handy for this huge codebase).

Anyhoo, I cleaned out my build dir and oldconfig'ed my 3.9 config, this
time saying no to everything new. As it turned out, the resulting config
was almost identical to my old 3.10 config (except for some crypto stuff
built as a module instead of built-in).
Now I don't have the freezes anymore. One possible reason is that I'm
now using 3.10.4 instead of 3.10.1. Another (more probable) reason is
that I may have forgotten to make clean the first time, which left over
some interfering cruft.
