Subject: IDE driver for HDD WDC WD1600JB-00R 160G

Hi all!

I have HDD WDC WD1600JB-00R 160G

$ grep -A 1 -B 1 WDC /proc/scsi/scsi
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: ATA      Model: WDC WD1600JB-00R Rev: 20.0
  Type:   Direct-Access                    ANSI  SCSI revision: 05

Kernel version: 2.6.38.2
Config in attach

It not always works correct
When I write to it, or sometimes just read from it, it cat slow down
all system, first there is a messages in logs (dmegs command):

And some times after this messages, system not respond, and Magic
SysRq doesn`t helps too (reboot key)
Is there any way to fix this?
