No dead disks, but after two days testing tcq patches (on 2.4). I got the two ATA errors (smartctl said). I think that it's no good to test tcq on IBM disks. My disk was without any problems one year. Two problems now is not normal. For final i think, that tcq patch is not fully stable, becouse on high disk load i get oops and have to reboot. I have no problem when i remove tcq patches. (high load i mean copy cca 20GiB between two IBM disks).
