This is with kvm-81
I'm getting a kernel panic when I modprobe kvm-amd
It used to work until I had to use the CMOS jumper to boot.
The motherboard is an Asus M3N78 PRO
The CPU is an AMD Phenom 9950 Black Edition
Here are the steps I've already tried:
- Checking that virtualization is enabled in the BIOS
- Updating the BIOS
- Restoring the defaults of the BIOS
- Downgrading the BIOS
- Trying various versions of kvm
- Trying various linux kernel versions
- Trying various vcore settings
- Enabling/Disabling Cool & Quiet and AMD C1E
- Tried a known good kernel and modules combo
- Interrupting the boot process to only have udev as a process, and killing it.
- Not having any other modules loaded
What I plan to try:
- Updating to 2.6.28 and kvm-82
- Tranfering the nvram from an identical motherboard I own to the
problematic one, using /dev/nvram
Here are the traces

Joerg, all I can make of it is that svm is enabled on one cpu but not on
the other. Can you help here?

This is resolved, but since other people might have the problem I'll still
post what I figured out. It seems like a strange corner case of memory
allocation.
I've upgraded to kernel 2.6.28 with kvm-82, but the problem kept
persisting. I've decided to remove the evga 9800gt and suddenly it kvm-amd
would load without any issue.
I've decided to check the Asus website and sure enough there was a bios
update, I've installed it then installed the evga card back it and since
then everything works (well except rebooting but anyways).
The bios update is 0603, it lists fix ups for some memory modules as an
improvement, so that might be it.

This looks like that the BIOS did not load the same microcode patch in
any individual core. So some cores have SVM disabled which triggers the
#GP. I guess this is a BIOS bug.
