(I'm guessing its ecx or esi; nothing else makes much sense.) I submitted an earlier report with a more complete dump of this function, which is at http://lists.xensource.com/archives/html/xen-devel/2010-02/msg00844.html The code may have changed slightly since then but it looks to be the same issue.
