Errors on ICH10R with Seagate HDDs

[Thomas Jackowski <aXe@hadiko.de>]

Hi,

I assume a problem between Seagate Drives and the ATA Drivers.

Chipset is a ICH10R, but this problems has been seen on a ICH9 also.

=== START OF INFORMATION SECTION ===
Model Family:     Seagate Barracuda 7200.11
Device Model:     ST31000340AS
Serial Number:    6QJ03QBN
Firmware Version: SD1A
User Capacity:    1,000,203,804,160 bytes
Device is:        In smartctl database [for details use: -P show]
ATA Version is:   8
ATA Standard is:  ATA-8-ACS revision 4
Local Time is:    Fri Mar 27 10:58:37 2009 CET
SMART support is: Available - device has SMART capability.
SMART support is: Enabled

This is /dev/sdc. /dev/sdd and /dev/sde is the same model with the same 
Firmware. I'm using a RAID5 on these 3 HDDs.
Because of the Seagate Firmware Bug I had to upgrade the firmware from
'SD15' to 'SD1A'. The upgrade was successful.

Before the upgrade there were no problems, after the upgrade I have 
trouble like this:
