hi i have similar problem.
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).
