> Subject: [PATCH] event/sw: remove stale IQ references when reconfigured
>
> This commit fixes a bug in which, when the sw PMD is reconfigured, it would
> leave stale IQ chunk pointers in each queue's IQ structure. Now, the PMD
> initializes all IQs at eventdev start time and releases all IQ chunk
> pointers at eventdev stop time (which has the consequence that any events
> in a queue when the eventdev is stopped will be lost). This approach should
> be resilient to any reconfiguration done between the stop and start, such
> as adding or removing queues.
>
> This commit also fixes two potential issues in iq_chunk.h. iq_init()
> now initializes the IQ's count field to 0, and iq_dequeue_burst() sets
> iq->head to the appropriate next pointer.

After reproducing the error reliably, I can confirm this patch fixes here.
Also, I think this patch deserves a reported by tag. Perhaps it can be added on
apply?
