If "acpi=force" helps, it is an issue with detecting acpi and may show in the dmesg log. It is not an issue with handling shutdown. Since it used to work, you should compare dmesg logs from a working and non-working kernel, and with and without "acpi=force", and file a bug against the kernel. That way it can be fixed. -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/>
