Heh :) The failure is (IIRC, I don't have the serial logs to hand)
before ide_start_power_step() is called. We get to start_request(), and
the system then fails with "bus not ready on wakeup" and "drive not
ready on wakeup". Calling the _GTM and _STM ACPI methods before then
lets the system come back up normally.
