Bingo! I switched from ata_piix.c to piix_ide.c and the "pop" disappeared. I must say that the "pop" also disappeared after suspending to disk using suspend2 (obviously without executing halt -n -h -p) . In both cases it was present with the previous setup. This is with a pure PATA setup with no SATA ports and the disk is: hda: TOSHIBA MK8025GAS, ATA DISK drive Many thanks! regards, Fabio On 4/19/07, Chuck Ebbert <cebbert@xxxxxxxxxx> wrote:

No click and the "retract" counter does not increment. (Even this procedure incremented the counter until I changed the script.) Seems safe, using the IDE drivers, since they sync the cache anyway. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
