[Bug 39499] Re: System doesn't power down under Dapper 686

[Tommy Trussell]

I just discovered the system behaves as expected if I add acpi=force to the kernel parameter in grub. When I do so, two ACPI messages appear in the startup messages, and when it comes time to shut down, the power goes off as expected.

This makes for a workaround, but what would it take to make it work correctly under the 686 kernel as it does in the 386 kernel? 

When I boot the 386 kernel, the ACPI boot messages do NOT appear, but on shutdown, the system halts, the motherboard beeps three times and the power goes off as expected.
