Hi,

I have successfully set up a xen-unstable machine with kernel 3.0, on an 
old core2duo - running win2008 in hvm works 100%.  When trying on a new 
i5 machine though, the same kernel reboots the machine immediately after 
xen starts up dom0.

It appears to be during the stage of graphics/framebuffer initialisation 
but the serial console does not show any details.  I have tried 
nomodeset with no changes.

What would the xen-gurus need from me to debug this in more detail?  The 
machine (same xen 4.2) boots fine with the 2.6.32.xendom0 kernel.  I was 
expecting at least an exception, core dump or freeze, but this reboot is 
quite strange and very hard to debug.

Thanks!
Andi
