There are two differences between create_workqueue(name) and alloc_workqueue(name, 0, 0). * The former has WQ_MEM_RECLAIM set and forward progress is guaranteed regardless of memory pressure. In this case, this shouldn't make any difference. * The former has @max_active set to 1 while the latter to WQ_DFL_ACTIVE. IOW, works queued on the same CPU would be allowed to run concurrently while before conversion only different CPUs can run works queued to the workqueue in parallel. This usually shouldn't make difference either as works could have run in parallel on different CPUs before too. Does alloc_workqueue(name, 0, 1) fix the problem? If so, it might be that the current workqueue usage has problem too.
