It always happens under heavy load, or when using smartmontools when
depth_queue is > 1. I've 2 drives and both of them have the same
problem (different firmware versions).

#hdparm -i /dev/sda
Model=ST3500630AS                             , FwRev=3.AAD   , SerialNo=       
     6QG0FMYJ
#hdparm -i /dev/sdb
Model=ST3500630AS                             , FwRev=3.AAE   , SerialNo=

Test in a ICH7 controller that can do ncq sucessfully (tested) with
other drives (for example, Maxtor 6V250F0)
