This one has been around for a while. It's been plagueing me since 2.6.8,
though its interesting that you only see it happening recently.

My attempts to debug it led to the bug disappearing when I added
instrumentation to the kernel.  On my Compaq Evo, it does power off
eventually, though it takes about a minute after that last
acpi_power_off message.

There are bugs open on this in bugme.osdl.org, and bugzilla.redhat.com
