Usually this is a symptom of Xen having the wrong idea about where to
send the console output.  Does adding 'console=vga' to the xen
command-line help (assuming you're not using a serial console)?  Did you
build your own Xen kernel or are you using the binaries from XenSource?

I've had another report of this behaviour today, also on Dell hardware
(PowerEdge 1750 and desktop), so it might well be a bug in mboot.c.
If you can send me the kernels and configuration files you're using,
I'll try to reproduce the problem here.

Shouldn't be; I've built mboot.c32 with that version of GCC before.

Cheers,
