no 3.3.1 is the current one, 3.3.2 is current

but the whole 3.3 line until now elaborates on the same problem
not at each boot, mostly only slower but terrible at all

https://bugzilla.redhat.com/show_bug.cgi?id=806548
https://bugzilla.redhat.com/show_bug.cgi?id=805317

i post a copy to the devel-list
maybe someone cosiders "CONFIG_RCU_FAST_NO_HZ=n" because
this is the change in 3.3 and seems to be the root cause
of all this troubles

my first bug report is now more than a month old and
there are built one kernel after the next with the
same problem

The bug report suggests this was about a kernel feature
(CONFIG_RCU_FAST_NO_HZ=y) and not related to systemd, no?
