[Xen-devel] infrequent kernel crash just before reboot

[Sander Eikelenboom <linux@xxxxxxxxxxxxxx>]

Hi All,

Once in a while when i try to reboot my machine the kernel crashes, because 
it's so infrequently i haven't been able to capture it via a serial log yet.
I have made 2 photographs from what's left on screen from the oops.
Machine is running :
