Looks like your card reader is not USB based, but SDIO. Thus corresponding SD card driver is sd/mmc block driver but not usual usb-storage. I thought, if your case is not an exception, maybe it is caused by bad JMicron host controller driver. We have similar platform (Eeepc) as yours, but never see such critical issue.

Apparently everything work fine. The problem is when the laptop goes in hibernation (I mean when I close the monitor), on the wake up the sd card is totally messed up , no more partition and the partition table is lost. Anyone know how I can avoid this problem?
