I don't think this patch has to be reverted, but I still think that it's
better to notice the reverse engineers team about failing operations
and understand the real problem rather than hiding it. Which works in some
cases, but sometimes just hide other bugs.

I'm almost done with rewriting the whole A/G/N setup and init routines,
following the new v4 specs. This issue could even be related.
