OOPS in kernel driver

Hi,

I'm using a somewhat "old" kernel with KVM (KVM included in the kernel).
I think it may be KVM-17 or something like that. Anyway, I got an OOPS
in the module while attempting to install Windows Server 2003 Standard
Edition 32-bit.

I just started it with
  kvm -no-acpi -cdrom w2k3.iso w2k3.img

w2k3.img is just a 5G raw image disk.

Linux mira 2.6.21-rc6 #3 SMP Fri Apr 6 02:04:27 CDT 2007 i686 GNU/Linux

processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 75
model name      : AMD Athlon(tm) 64 X2 Dual Core Processor 3800+
stepping        : 2

The OOPS is attached as you probably do not want it reformatted by the
email client.

PS. I know. I probably should have used more than 128M ram for the w2k3
server. But KVM shouldn't cause an oops regardless.
