It is also possible that this virtual disk has never worked with ata_piix driver and worked with piix driver in the older kernels because of pure luck. In 2.6.28 I've fixed LBA48 checks in IDE to match libata (see commit 942dcd8 for details) so it would be worth to try: - simulating the older buggy IDE behavior with 2.6.32 kernel or - staring long enough at 'hdparm --Istdout /dev/sda' output first. -- Bartlomiej Zolnierkiewicz -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
