I'm at a complete loss. Does NMI change > cache protocol? I've been looking thru Intel/AMD manuals, but nothing.... I should clarify I made nmi_callback volatile before adding prints. Moreover, I also put wbinvd() after set_nmi_callback, still same behaviour. thanks mukesh _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
