An integrated circuit device includes a processor core, and a controller. The processor core issues a command intended for a first thread of a plurality of threads. The controller initiates de-allocates hardware resources of the controller that are allocated to the first thread during a thread reset process for the first thread, returns a specified value to the processor core in response to the first command intended for the first thread during the thread reset process, drops responses intended for the first thread from other devices during the thread reset process, completes the thread reset process in response to a determination that all expected responses intended for the first thread have been either received or dropped, and continues to issue requests to other devices in response to commands from other threads of the plurality of threads and processing corresponding responses during the thread reset process.
