The new driver registers a "reboot notifier" with the system. If MD continues to perform I/O after the aic7xxx driver's notification routine is called, the result is undefined. The aic7xxx driver has already shutdown the hardware. Perhaps I should use a different event to indicate it is safe for me to clean up the hardware?
