Re: [Xen-users] Identical Win3K3 domU's. One panics dom0, other runs fine

[Don Faulkner <dfaulkner@xxxxxxxxxxx>]

Your assumptions are correct. Order doesn't matter; perseus always 
causes the panic regardless of whether cepheus is already running or 
not. The vif's are commented out for debug purposes only.
I'll report this to both xen-devel and the Ubuntu Kernel Team (since 
they apparently maintain the xen kernel too). Thanks.
