      "value": "An optional feature of PCI MSI called \"Multiple Message\" allows a\ndevice to use multiple consecutive interrupt vectors.  Unlike for MSI-X,\nthe setting up of these consecutive vectors needs to happen all in one\ngo.  In this handling an error path could be taken in different\nsituations, with or without a particular lock held.  This error path\nwrongly releases the lock even when it is not currently held.\n"

      "value": "Una caracter\u00edstica opcional de PCI MSI llamada \"Mensaje m\u00faltiple\" permite que un dispositivo utilice m\u00faltiples vectores de interrupci\u00f3n consecutivos. A diferencia de MSI-X, la configuraci\u00f3n de estos vectores consecutivos debe realizarse de una sola vez. En este manejo se podr\u00eda tomar una ruta de error en diferentes situaciones, con o sin un bloqueo particular mantenido. Esta ruta de error libera incorrectamente el bloqueo incluso cuando no est\u00e1 retenido actualmente."
