That was the rare case when resume worked at all... in most cased I've go= t reboot, before anything appear on the screen (even backlight is off) - xe= n panic? dom0 kernel panic? I've already rebooted the system, will try above debug key next time. I don't have serial console, but have USB-to-serial port - is it possible= to use it as xen console (in xen 4.1.3)? --=20 Best Regards / Pozdrawiam, Marek Marczykowski Invisible Things Lab --------------enig294C97DFEFAF07894B7CFEF5 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with undefined - http://www.enigmail.net/ iQEcBAEBAgAGBQJQuNmpAAoJENuP0xzK19cs9VYIAJn4wF1v3BuftMQIFeFuyKvi WsFn2taQEKaJ77mODvv7gu5qHOAZU8qf8JWoouePKRvHfDtN5/iASHo8myLipCBX qxGk1p9u6+rsHoRh7i65EthKc1fyIX9KWp5ZNLVHZSLH6imT8d+RcNH45Xv+HMX4 1jOgpO0lXi3JSvvsbRAvkAG/2ZNZdsonjplCty+hQCeWrNCeM+snWe+YOwaJMzT5 s3mp2XTR8lmJc7AZQHswA9pOgRu9Ym4lzV9njLScFQ5c2QZD6zexon8g+rAhIf+8 dKmo7t8cXkI0xrk+fZhstkEbgKdVFm/UkGMx/azfAN5mVklRYvfq1FZVUDzTcg4= =rxGb -----END PGP SIGNATURE----- --------------enig294C97DFEFAF07894B7CFEF5-- --===============6056331424479770381== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel --===============6056331424479770381==--
