Hi,
somehow the sil3114 causes data corruption with some (newer?) disks. Simply
filling the filesystem with zeros and reading the these data will make the
kernel to report filesystem corruption.
This is definitely not an issue of memory, since the systems (several tested)
do have ECC memory and the memory is monitored with EDAC.
Also not an issue of the filesystem, also several tested.

The ST3250820AS data on the ST3250820AS disk will suffer from data corruption,
but the data on the older ST3200822AS will *not*.
kernel versions tested: 2.6.15-2.6.20
Any ideas how to proceed?
Thanks,
Bernd
