The 20161202.n.2 build cannot boot up

[Bowen Wang]

Hi everyone,
I just run the command
dnf upgrade --refresh
to update to the 20161202.n.2 build
but after I updated the system, it cannot be boot up, it will be stuck in
the boot process
there will 3 places that the boot process can be stuck in
1. the output
started gnome display rook ... service some_other_stuff
2. the output
started virtualization daemon hook... service some_other_stuff
3 the output
install ABRT coredump ...some_other_stuff

And it is also useless to use the older kernel to boot up. Pretty weird.
is there any problems in the latest build?

Sincerely,
Bowen Wang
