sata exception

[ryabserg]

Hi all,
I have a similar problem with different new HDD (WD, Seagete) on different hardware.
Neither the SeaTools nor the MHDD not reporting any errors. Under OS Windows XP SP3 everything works fine.
Problem began after some period of working, under different versions of linux, bug was tested on:
Debian Linux tester 2.6.26-2-686 #1 SMP Fri Aug 14 01:27:18 UTC 2009 i686 GNU/Linux
Ubuntu Linux version 2.6.28-15-generic (buildd@yellow) (gcc version 4.3.3 (Ubuntu 4.3.3-5ubuntu4) ) #49-Ubuntu SMP Tue Aug 18 19:25:34 UTC 2009

In an attachment is a collection of other log files.

Here is part of kernel's log, starting from an error:

Anyone know what causes it?
Thanks,
