External USB 3.0 drive is not mounting properly at reboot

Static IP didn't help. That's why I was thinking, that it might be a drivers problem with the WiFi card. But I had no time yet to take out the card.

So, I took out the PCI-E Wifi card but still had the same Problem with stucking "Setting up resolvconf" on booting into bpo 3.16. I tried both, fixed IP and DHCP.

I did not setup any DNS, isn't OMV getting DNS via DHCP?

resolve.conf

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 172.16.1.1
search fritz.box

interfaces

# The loopback network interface
auto lo
iface lo inet loopback
iface lo inet6 loopback


# eth0 network interface
auto eth0
allow-hotplug eth0
iface eth0 inet dhcp
iface eth0 inet6 manual
    pre-down ip -6 addr flush dev eth0

The fritz box is just resolving as domain controller. DNS is working fine, internet access or access to local network devices is no problem.
I also tried boot delay of 60.

Just want to bring every thing together:
Kernel 3.2
Boot delay of 5 is good for mounting, DHCP is working USB 3.0 is very slow.

Backports 3.16
Boot delay of 10 is good for mounting but boot stucks on "setting up resolv"

Realtek firmware is up to date.

So the main problem is solved, maybe I open a new thread for the network resolv problem.
