Assume that a Secure Digital (SD) memory card slot is enabled on a Windows Vista-based or Windows Server 2008-based computer. When you try to put the computer into either standby or hibernation, the system stops responding (hangs).
This problem occurs randomly.
This problem occurs if an interrupt occurs on the shared interrupt line when the system is entering standby (S3) or hibernation (S4). In this situation, the Sdbus.sys driver incorrectly claims interrupts, and then the driver schedules a deferred procedure call. This behavior occurs even though individual SD sockets are already shut down. Therefore, the interrupt source is never serviced, and the system stops responding.
