(the same hardware) On 2.6.38.3 xenlinux kernel after resume there is screen content from bef= ore suspend, power led light constantly (as it should), but system is irresponsible (no capslock led, no reaction to sysrq, network etc). On 3.x with your patches system goes into S3, but on resume is even worse= - no screen content at all (and no backlight) and also irresponsible, power le= d still blinking. As 3.x tried: - your devel/acpi-s3.v7 branch directly - 3.2.7 merged with devel/acpi-s3.v7 - 3.3-rc4 with devel/acpi-s3.v7 - your devel/acpi-s3.v8 branch directly The same result on all above. How can I debug this issue? --=20 Best Regards / Pozdrawiam, Marek Marczykowski Invisible Things Lab --------------enig0B75A1C5E85F4DE3A83A9DBD 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 Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJPRuF1AAoJENuP0xzK19csvXMH/isCx9LxT1zDNn5xVfU4OEte F7GrfgkL5U7FpJJG1Ve/Dd9zy5l1gzWbfjtHp0KrB3e2rlxFJupGupckGh+p29cn SMr33edanNTVcpez16Zh8f0wiOiWP2psnnB5R+pwheogqcAu83UrQDmTUsi87qhL St871/thcUYO63kkZk1vQWqOCpwa3FZ/eDY4zgySc2mhkal+3/i0W7NssX//qLhp Fd8rWVvG+EkWNyA6KmiCE+lw1pVF9k5i8binoj1QZ/EeYaKAoyqEanNMnSK5hq+8 bEIcfZpCQOL+4OR2z1e1mu/uQxU7w9JvX5PpJ1WHgWkQ6AeZBshKIgprFCA5hGE= =Q3M3 -----END PGP SIGNATURE----- --------------enig0B75A1C5E85F4DE3A83A9DBD-- --===============1048643412374623495== 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 --===============1048643412374623495==--
