Hi,

I have a Toshiba Portege M400 laptop with a core2duo T7200 CPU. It kernel
panics when I insert the kvm-intel module:-

This is what I have transcribed from the screen:-

System information (dmesg etc) can be found as attachments on a bug filed
against my distro:

https://bugs.launchpad.net/ubuntu/+source/kvm/+bug/120021

It was suggested that maybe my BIOS was not configuring vmx correctly. Are
there further BIOS tests I can perform?

Cheers,
Al.
