Adding apic_verbosity=debug gives me that (hope nothing miss-typed as I have no serial console on this box).

Thanks for your ideas, Sean ! >The bug is not likely to be corrupted data in the decompressed output (that is just calling into a gzip routine or something). You shouldn't have to dump/printf->trace from memory during boot to see that data since the "real" kernel binary that is being decompressed into that memory region is probably already somewhere > in your build tree

I am trying to get QNX working with Xen. I''ve going about it in a similar way as installing windows with Xen, but when I start the guest up to install the OS it hangs on the line: ''Hit Esc for .altboot.......'' If anyone has managed to get this working, or has any ideas/advice for me here it would be greatly appreciated! Bryan
