        Using config file "/etc/xen/nbsd".
        Started domain nbsd
        xenconsole: Could not read tty from store: No such file or directory
        %
        
        an old kernel with the same kernel config works fine.

        i've put some files at ftp://ftp.netbsd.org/pub/NetBSD/misc/yamt/6/.
                20080112.gz     working kernel (gzipped)
                20080113.gz     not working kernel (gzipped)
                nbsd            /etc/xen/nbsd (see above)
                XENU            a kernel config
