Please never mix packages from virtualbox.org and virtualbox packages from the ubuntu archive.

You are right !!!

from Oracle:
Note: Ubuntu/Debian users might want to install the dkms package to ensure that the VirtualBox host kernel modules (vboxdrv, vboxnetflt and vboxnetadp) are properly updated if the linux kernel version changes during the next apt-get upgrade.

So the ubuntu archive might need some cleaning, as these virtualbox-ose packages seem outdated now (ex SUN packages) & virtualbox-dkms simply replaced by dkms dependency.

This bug was fixed in the package virtualbox - 4.1.6-dfsg-2

---------------
virtualbox (4.1.6-dfsg-2) unstable; urgency=low

  * Fix build errors with kernel 3.2. (LP: #892506)
    - Add 36-kernel-3.2.patch, cherry-picked from upstream.
  * Make dependencies of the dkms packages on virtualbox/virtualbox-guest-utils
    versioned.
  * Move VBoxDbg.so to virtualbox-qt as it's a GUI component.

Problem is still there with the latest kernel & virtualbox-4.1:

oem@oem-desktop:~$ sudo /etc/init.d/vboxdrv setup

 * Failed, trying without DKMS
 * Recompiling VirtualBox kernel modules
 * Look at /var/log/vbox-install.log to find out what went wrong

Some kernel change related to iommu seems to break the Oracle package:

https://lkml.org/lkml/2011/6/22/106

/var/lib/dkms/vboxhost/4.1.6/build/vboxpci/linux/VBoxPci-linux.c have some #include entries:

#include <linux/intel-iommu.h>
#if LINUX_VERSION_CODE < KERNEL_VERSION(3, 1, 0)
# include <asm/amd_iommu.h>
#else
# include <linux/amd-iommu.h>

we can see they are not found apparently:

oem@oem-desktop:~$ sudo find / -name amd-iommu.h
[sudo] password for oem:
/usr/src/linux-headers-3.2.0-2/include/linux/amd-iommu.h
/usr/src/linux-headers-3.2.0-2-generic/include/linux/amd-iommu.h
/usr/src/linux-headers-3.2.0-3-generic-pae/include/linux/amd-iommu.h
/usr/src/linux-headers-3.2.0-3/include/linux/amd-iommu.h
/usr/src/linux-headers-3.2.0-2-generic-pae/include/linux/amd-iommu.h

so its amd-iommu.h (with hypen, not underscore) & kernels are 3.2 of course.

This issue is not only an Ubuntu issue:

virtualbox-4.1 is not a package from the Ubuntu repository.

Still getting lots of duplicates from users of Ubuntu 12.04 running virtualbox-dkms 4.1.2 (the version from Ubuntu 11.10).

It appears perhaps virtualbox-dkms does not upgrade properly when you upgrade ubuntu 11.10 to 12.04. Because users of Ubuntu 12.04 should have virtualbox-dkms version 4.1.12, not 4.1.2:

Being anonymous in NA really means not telling people who ELSE is a recovering addict. You can say whatever you want about yourself and your experience to whomever pleases you. The other part is that it's not suggested that you run around going on Good Morning America or local radio programs crowing about how you're an NA member, but that has nothing to do with making announcements on FaceBook or Reddit or during an office meeting.

Subject: GPU sag. It does happen

I'm curious as to why the NBA used a different soundbite for the Lillard game winner. In the actual video you can hear Mike Tirico say Lillard Good! Lillard Good! But in this one they used a section from a different call where he yells Bang! Personally, I preferred the original one because Tirico sounded a lot more exhilarated in that call.

i cant comment on the top post from you first post. so ill just add it here.

When i was young i spent alot of time around cars. My dad always went mudding/4 wheeling while we lived in virginia. he also worked on a small time circle track team. we moved to texas and he somehow fell in wirth a local top alcohol dragster team and had friends with various projects. i had learned my way around a car and knew how to use tools. When i was 15 i got my learners permit, when i was 16 i got my license, the next day my dad drove up in a 1991 Mitsu Eclipse. He told me it was mine, but, before he would give me the keys i had to change the tire. He told me the manual was in the car and would instruct me on lift points and so on. he sat outside and watched to make sure i didnt kill myself, but i changed the tire. it took me almost 2 hours to do so, but i did it. A few weeks later i was at school and some chick with a car full of dudes had a flat and none of them knew what to do. i saved the day.

the first time my brakes went out on the car my father did the same thing. he bought the pads and told me to figure it out. luckily brakes are easy to figure out. he made sure i didnt kill myself and i was able to do it.

since then i have done most of the work on al of my cars, and i have no real training. all of this was before youtube and when forums werent really a thing. now, im 30 years old, and i have a project car (98 328is drift car) that i work on, just from problem solving. no money, but i buy what i can. nowadays youtube and forums are great. i still thank my father for teaching me, or at least overseeing what i was doing. taught me to do things myself. i cant stand to see people on facebook groups asking "need someone to change my brakes" and their excuse is "dunno how" or "no tools" harbor freight and the internet leave no room for excuses.

Vince McMahon - at least as far as direct creative control goes. I say, give Trips a chance to really see what he can do in that position. Things going on in NXT are exciting, but I see it not just as developmental, but also a bit of a sort of incubator to experiment with ideas about the business (including financial models). Try it in NXT, incorporate into Smackdown for refinement (obviously, WWE would know far better than I, but I intentionally picked the brand with what I think is a different sort of audience than NXT), perfect it on RAW.

Bonus is that when you bring someone up from NXT, they're already familiar and have worked with whatever-it-is-you're-doing. So, they learn the style as it quite literally is being created. They can take that and do a (business buzzword alert) knowledge transfer to the regulars on Smackdown/RAW. In other words, by going through the process of paying their dues on the main stage, all of the performers working with them get to learn and practice the things the company has been experimenting with in NXT.

It wouldn't surprise me in the least if this is precisely what The Game has in mind.
