Commit 8a2e8e5dec7e29c56a46ba176c664ab6a3d04118 (workqueue: fix
cwq->nr_active underflow).  The symptom described in the patch
description is different but nr_active is used for workqueue freezing
and can definitely lead to malfunction during freeze.  I've sent pull
request to Linus yesterday.

Thanks.
