I don't want to destroy your new-found happiness, but maybe I should be more
specific on what we found out:

* hanging when making to many calls to printf() with dynamic strings, ie. %, is gone
* hanging when receiving more than we can consume still hangs the process:
  30 bytes every 2ms at 115k2 on 50MHz -> eventually freezes the process. And INTR
aborts it.
