Es necesario activar el controlador kthread. Esto puede ser demasiado pesado en caso de recuperaci\u00f3n, como por ejemplo: - N colas de hardware - la profundidad de la cola es M para cada cola de hardware - cada scsi_host_busy() itera sobre (N * M) etiquetas/solicitudes Si la recuperaci\u00f3n se activa en caso de que todas las solicitudes est\u00e1n en curso, cada scsi_eh_wakeup() est\u00e1 estrictamente serializado, cuando se llama a scsi_eh_wakeup() para la \u00faltima solicitud en curso, scsi_host_busy() se ha ejecutado (N * M - 1) veces y la solicitud se ha iterado durante ( N*M - 1) * (N * M) veces. Si tanto N como M son lo suficientemente grandes, se puede activar un bloqueo duro al adquirir el bloqueo del host, y se observa en mpi3mr (128 colas hw, profundidad de cola 8169). Solucione el problema llamando a scsi_host_busy() fuera del bloqueo del host. No necesitamos el bloqueo del host para obtener el recuento de ocupaci\u00f3n porque el bloqueo del host nunca cubre eso.
