It went into rc1, but the hang in an usb device (1-1.3) shows up only with rc3. Why is device_suspend() called anyway if the system will go down anyway in a few milliseconds? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
