Default slow sd mount afet .757

after updating to .757, most bugs including the notification sound bug is gone. but i also noticed on boot up and after connecting to pc, my sd card takes a long time to mount. when i was in 4.3, as soon as the phone boots up, i can access the sd card right away. but now, after booting up it takes another 1-2 minutes before it even have a notification of mounting sd card, than takes another 5-6 minutes before its loaded in the system.

am i alone?
