Window 8 may stop responding (hang) when multiple abort commands are sent to an embedded storage device

Symptoms
Consider the following scenario:
  • Windows 8 is installed on a computer that uses an eMMC embedded storage device.
  • The eMMC embedded storage device performs a NAND management activity that lasts longer that one second.
  • The Windows 8 SDBUS.sys driver detects an I/O request time-out and then starts a recovery.
  • The Windows 8 SDBUS.sys driver sends an abort command (CMD12) to the eMMC device.
  • The embedded storage controller also sends an abort command to the eMMC device.
In this scenario, Windows 8 may become unresponsive, and you may have to restart the computer to clear the condition.
Cause
This problem occurs because the eMMC embedded storage device does not handle two concurrent abort commands when the device is busy because of internal NAND management. The storage device does not send a response to the abort command that is issued by the controller. This triggers the SDBUS.sys error recovery flow again, and the device never recovers.
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
