kvm crashes on load (exception 12)

Public bug reported:

Binary package hint: kvm

I've kvm (16-1ubuntu2) installed. When I try to install the
ubuntu
server (feisty) CD image, the following error message is
printed:

exception 12 (0)

With kvm 18-1ubuntu1 I didn't get this error message, but
kvm didn't
work with this version.

To sum up: version 18 can't use the kernels kvm module, and
version 16
crashes.

I can reproduce this every time with kvm_16-1ubuntu2 on an
HP Compaq
dc7700p desktop system with Intel VT enabled in the BIOS
(v2.09) running
Feisty x86_64 (kernel 2.6.20-15). This happens with out
without -no-acpi
or -no-rtc.

My system log has hundreds of lines like the following:
[ 3271.013496] rtc: lost some interrupts at 1024Hz.

with the occasional:
[ 3229.167184] kvm: msrs: 6

A gdb backtrace is attached (but it's probably useless,
since kvm is
compiled without debugging symbols).
