I had to disable local apic during kernel compilation: on 2.6.8.1 the
noapic didn't work from me, or at least didn't solve the shutdown
problem, while not compiling it in the kernel allowed my tp to power
down.

To disable during kernel compilation go under Processor type and features
then disable Local APIC support on uniprocessors.

Hope this helps.
