Yes it is reproducible.

1/ Connect the USB drive. It mounted works OK.
2/ After about 10 to 15 minutes of not using the drive, the system would get into this situation.

I am using Maxtor OneTouch and Wester Digital FreeAgent. To remount the disks, I need to turn them off and on again; then it will works.
