thanks renato, I believe that the hypervisor portion of xenoprofile is
sending
the correct mode, eip/rip values. I'll get with Ray and see if we can
track
down where the issue might be (oprofile or hv, or configuration issue).

We'll definitely let you know if we need some assistance in the oprofile
area.
Any idea when will 0.9.3 be out? I know that some of the distros are
trying to add your xenoprofile patch on top of 0.9.2 for their releases,
and having 0.9.3 would be easier that already contained the xen patches.
