When my CD drive spins down, it immediately goes to STANDBY mode, as reported by the ATAPI CHECK POWER MODE command. According to the ATAPI specs, an ATAPI device may take up to 30 seconds to go into ACTIVE mode again. As the FreeBSD ATAPI driver doesn't check for the device's current power mode, it times out long before. I'm currently trying to add the necessary code to the ATAPI driver in order to check for device's power settings and will post my diffs as soon as I'm done.
