Ok, this was causing a bug at least in *-sedf-* related tes runs, for
which I just sent a fix (<cbd6b5a7d0451a98a8c6.1340212196@Solace>,
[PATCH] xl: fix sedf parameters checking).

Basically, when not specifying explicitly the sedf scheduling
parameters, one couldn't even start a new domain.

I'd swear I tested that case, even more than once, but I apparently am
wrong. :-(

Anyway, sorry for both that and not noticing this sooner. As soon as
we'll have the fix committed (provided you like it) we can see what
happens to both the -sedf and non -sedf runs in future flights. I know
the bisector is something to be trusted, but I really hope to see the
issue for non -sedf cases to be caused by something else, as I can't
reproduce it and neither I can see how that could happen. :-O

Thanks and Regards,
Dario
