I looked into this when you suggested it, but it latches the wrong eip in the emulation state, and you will end up re-emulating the ud2a instruction, rather than the following instruction. I would be tempted just to leave this code in its current condition. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
