Symptoms

When 2000/4000 platforms return an error condition to the TMM driver, the number of active requests are not decremented. This can cause hardware compression to stop adding jobs to the hardware queue.

Impact

When this occurs, the system might show a drop in performance. CPU usage might report as very high, and hardware compression jobs are no longer queued.

Conditions

This occurs on 2000/4000 platforms that return an error condition to the TMM driver.

Workaround

None.

Fix Information

In this release, the system correctly decrements active jobs counter when this error is detected. CPU no longer runs high, and jobs are assigned to the correct compression queue.
