Bug#296623: kernel-image-2.6.8-amd64: 2.6.8 kernel images panic on quad Opteron box

[Alex Page <alex.page@cancer.org.uk>]

Package: kernel-image-2.6.8-amd64
Severity: critical
Justification: breaks the whole system


I have installed Debian Sarge on a four-way Opteron HE box. The install went smoothly, and the default kernel-image-2.4.27-1-386 package seems to work fine. One of the first things I did was to install an 
Opteron-optimised, SMP kernel-image, kernel-image-2.6.8-10-amd64-k8-smp. This gave a Machine Check Exception on boot:

I have tried kernel-image-2.6.8-10-amd64-k8 which also gives a Machine Check Exception, and kernel-image-2.6.8-2-386 which just hangs at "Calculating Delay Loop".
