  Type: Direct-Access ANSI SCSI revision: 05

Software Environment:

Problem Description:
Writing data on a SATA drive sometimes (5 - 10%) failed. Files have the right
size but differ in their md5 checksums. Older kernel versions work fine
(2.6.10). The problems still occurs in the kernel version 2.6.18 from kernel.org
(Linux linux 2.6.18 #1 SMP PREEMPT Tue Oct 3 16:58:22 CEST 2006 x86_64 GNU/Linux)

I changed memory and harddisk (including cable).

Steps to reproduce:
copy same 100MB file some times and calculating checksum.

See also 6845 for another Nvidia + silicon image corruption example, but not
sure if they are the same root cause yet
