vboxdrv gives kernel preempt fault w/ cool n quiet disabled

Postby dralan » 8. Nov 2011, 22:23

Hello,

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.
[ 90.148043] general protection fault: 0000 [#1] PREEMPT SMP

[ 90.148123] RSP: 0018:ffff880226e95ed0 EFLAGS: 00010206
....

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:
http://forums.opensuse.org/english/get- ... ister.html
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.

Thanks!

These kinds of problems that are reproducible should be reported to bugtracker. You will need to setup an account there as it is on a different system.
It would also help if you can post the ticket number here so other can see the progress, add information, or see the final results.
