After I see the log, I tried with:
    root (hd0,0)
    kernel /xen-3.2-1-amd64.gz noapic
    modules /vmlinuz-2.6.26-1-xen-amd64 ....
    modules /initrd.img-2.6.26-1-xen-amd64 ...

This configuration as grub config works fine.

When try to pass apic=debug  to "kernel /xen-3.2-1-amd64.gz", There is
no debug message shown.
If you needs other info. Let me know please. :-)
