Could you try this patch on your system with acpi that
is having problems.
The patch needs some work before it goes into a mainline kernel
as I have hacked the call to acpi_power_off_prepare into roughly
the proper position in the call chain instead of use a proper
hook. But I can't quickly find an existing hook in the proper
location.
