i had this problem as well on a Sony Vaio VGN-BX560B. This box has an intel hda sound card. I was able to get the laptop to turn off by forcing he removed of the sound module.
I did this by adding the line rmmod snd-hda-intel to /etc/default/halt Hope this helps someone. -- Power down after shutdown does not work... https://bugs.launchpad.net/bugs/43961 You received this bug notification because you are a direct subscriber of a duplicate bug. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
