If Debian is using dracut it just requires adding in /etc/dracut.conf early_microcode=yes and from there on any regenerated initramfs will have the required microcode. Then 'ucode=scan' needs to be added on the Xen command line. But this is a shoot in the dark - this microcode update might have nothing to do with these failures. > > Ian. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
