I can say that the previous kernels boot just fine (3.3.0-8) and I have no
trouble with them. Any ideas on what I can look at? Maybe file a bug report?

I would try the current kernel first, 3.3.1-5, although I did not have any such problem as you report with 3.3.1-3,
x86_64.

no 3.3.1 is the current one, 3.3.2 is current

If you say so... my kernel is 3.3.1-5 and doing a software update assures me that "All software is up to date" so I have no idea where you get new kernels, unless you are running from testing or rawhide. In any case, a quick look at the subject suggests that the O.P. isn't even running updated production software versions.

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

can someone please take a look at this F16 report?

* boot sometimes terrible slow
* randomly boot fails with udev crashing / timeout
* shutdown terrible slow
* partly also on physical machines but not sooo slow

since most of the boot time is consumed by udev and
the terrible slow shutdown of>  30 seconds happens
while unmounting "old..." i guess this is not only
the kernel

feels like interaction between kernel/udev/systemd

on shutdown / reboot i can randomly see each single
unmounting line for 1-2 seconds, this is odd

i have virtual machines which booted in 5-6 seconds
and are now degraded up to 1 minute

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