ICH5-SATA file corruption under 2.4.21-ac1

On an Intel winterpark motherboard I'm seeing file corruption when
using the onboard SATA interface. The test I'm running is ctcs's new kdiff test which just copies a kernel, diffs it, deletes the tree, and starts over. (Which seems to find file system issues like this pretty quickly.) The error I'm getting look like this:

Random bit errors. This really doesn't look like an IDE layer problem to be honest.

What is the distribution of the file offsets where those happen ?
Distributions in terms of offset modulo 512/1024/2048/4096 ?

If they are always in the beginning of some sort of block, that is a tell-tale of its own, isn't it ?

When I switch out the drive for a pata drive everything works. Same
system, and OS config. This would seem to indicate an issue with the ide driver.
