Not if, as proposed, there was a kernel switch to enable including the HPA in the disc area. Also those who has such filesystems {c,sh}ould disable HPA in their BIOS (hopefully). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
