[Xen-devel] Re: 2.6.39 dom0 xen power management test

[Sander Eikelenboom <linux@xxxxxxxxxxxxxx>]

Hi Konrad,

First tests looked good, but tonight after approx. 2 hours after boot the 
machine crashed.
Since my previous setup ran perfectly stable for 55 days, i didn't have a 
serial console attached.
I shot a photo of what was left onscreen (attached), will attach a serial 
console later to get it all.
