Your backtrace shows this is not an ACPI problem, it's a problem with
vr(4) (the Via Rhine ethernet driver).  It should check flags to see if
the driver is going away in the device_detach case.  I'm not sure how the
intr handler got called since interrupts are disabled before powering off
the system.
