Hello!
I'm having a similar problem with a brand new Hardware under Fedora 9 x64 8GB RAM Motherboard: ASUS M3N-H/HDMI Chipset: NForce 8300/Nvidia 750a CPU: AMD AM2 5600+, 2.9GHz, Brisbane Dual Core Kernel: 2.6.25.9-76.fc9.x86_64 Smartmontools: smartmontools-5.38-2.fc9.x86_64 BIOS AHCI mode Power cables for ata3 and ata4 are on the same cable from an Enermax power supply.
ata1.00: ATA-7: SAMSUNG HD103UJ, 1AA01109, max UDMA7 ata2.00: ATA-7: SAMSUNG HD103UJ, 1AA01109, max UDMA7 ata3.00: ATA-7: SAMSUNG HD103UJ, 1AA01109, max UDMA7 ata4.00: ATA-7: SAMSUNG HD103UJ, 1AA01109, max UDMA7 ata5.00: ATA-7: SAMSUNG HD103UJ, 1AA01109, max UDMA7 ata6.00: ATA-7: SAMSUNG HD103UJ, 1AA01109, max UDMA7 scsi 0:0:0:0: Direct-Access ATA SAMSUNG HD103UJ 1AA0 PQ: 0 ANSI: 5 scsi 1:0:0:0: Direct-Access ATA SAMSUNG HD103UJ 1AA0 PQ: 0 ANSI: 5 scsi 2:0:0:0: Direct-Access ATA SAMSUNG HD103UJ 1AA0 PQ: 0 ANSI: 5 scsi 3:0:0:0: Direct-Access ATA SAMSUNG HD103UJ 1AA0 PQ: 0 ANSI: 5 scsi 4:0:0:0: Direct-Access ATA SAMSUNG HD103UJ 1AA0 PQ: 0 ANSI: 5 scsi 5:0:0:0: Direct-Access ATA SAMSUNG HD103UJ 1AA0 PQ: 0 ANSI: 5
Problem occours only on ata3, I've changed the disk Port 3 the third time (new disks) and changed the SATA cable, too. Problem still exists.
Sometimes a RAID rebuild doesn't work at all.
To get the drive to live I've to power down the system.
Logs are attached.
Can it be a bug on concurrent access of smartctl/smartd?
Any ideas?
Ciao, Gerhard

Hi Gerhard,
It /could/ be the port itself if you have changed the cable and disk..
Have you tried loading the disk with dd and seeing if you can reproduce the problem? You are getting the same error I get generally, I can recommend turning OFF NCQ first and see if the problem goes away.
# Define DISKS. cd /sys/block DISKS=$(/bin/ls -1d sd[a-z])
# Disable NCQ on all disks. echo "Disabling NCQ on all disks..." for i in $DISKS do echo "Disabling NCQ on $i" echo 1 > /sys/block/"$i"/device/queue_depth done
Justin.
