Bug Description
Description:
In our testing in UME beta3, before S4, we mount USB as /dev/sdb to /mnt/disk, and after S4 wake up, "df -k" shows that the /dev/sdb is still mounted in /mnt/disk, but the directory of /mnt/disk is empty. At the mean time, we notice that the USB disk device is turned to /dev/sdc.
Reproduce Steps:
(1)insert a USB disk
(2)mount the USB disk to /mnt/disk, for example, "mount /dev/sdb /mnt/disk"
(3)make the system go to S4
(4)wake up from S4
(5)check if the /mnt/disk is accessiable
Expected Result:
the orignal mounted disk is still mounted in the orignal mounted directory

Does this work correctly on the moblin kernel?
I believe this is related to USB_PERSIST patches upstream, have any of them been applied to moblin?
