That is what caused it. It would be of interest if you could disassemble init
and see what is the offending instruction (and around a couple of lines before 
it).
Use objdump for that purpose.

Also, please add these to your bootline to get more debug information (obviously
change your com1 and root line):

        root (hd0,0)
        kernel  /xen-3.5-unstable.4.gz com1=115200,8n1,0xd800,0

dom0_mem=2GB
        module /bzImage ro root=UUID=d6d08653-4a4f-4d41-87f2-f42fb7fe3ad5
