If no MACs were\nregistered, NAPI was never enabled. Also, if they were registered but\nsubsequently unregistered, NAPI was already disabled in\nmal_unregister_commac(). In either case, calling napi_disable() causes\nthe kernel to hang upon module removal.\n\nFix this by only calling napi_disable() in mal_remove() if the commac list\nis not empty (which implies NAPI is enabled).","state":0,"publishedAt":"2026-09-24T16:03:17.967+00:00","modifiedAt":"2026-10-03T10:58:04.56+00:00","affected":[{"ecosystem":"Vendor
