I have a relatively new system:
Asus M5A99X EVO motherboard
AMD FX-8150 CPU
I have noticed that if I leave AMD's "Cool N Quiet" feature on, which generates events for CPU scaling and voltage adjustment, vboxdrv loads perfectly. However, As soon as I turn it off, things get ugly:
[ 90.147865] vboxdrv: Found 8 processor cores.

To make a long story short, I've tried both the version that ships with OpenSuSE, 4.0.14, the latest from Oracle, 4.1.6, and both plain OSE and PUEL. I've also tried using the prepackaged kernel modules for 4.0.14, and building my own with 4.1.6. No matter what I do, I cannot get vboxdrv to load without enabling the cool n quiet feature. I always get a general protection fault of type preempt smp from vboxdrv.
I've scoured the internet and these forums for the past few days and it looks like I am doing everything correctly to build the modules. I did come across this however:

So it seems that I am not the only one with this issue. I can literally leave everything in the bios the same and just change the cool n quiet option, and that makes the difference between vboxdrv giving me a gpf and running fine.
Should I file a bug report? This is my first post on this forum.
