Anyone has an idea? About the problem starting a XEN kernel OR the
problem starting the normal kernel with hvmloader?
Is this probably a kernel bug? And if so, where can I report it? Is it
likely Xen is the problem or FreeBSD is the problem?
Do I need more information than this? I can provide everything(even
memory dump if that would help).

Kind regards
