Comment 38 for bug 297058

Same problems, hardware: Dell Inspiron 2200 (ATA disk). I replaced a drive because of the error and the new drive reports the same thing. I noticed the problems starting when I switched to Karmic (9.10).

A few lines from LSPCI:

00:1f.0 ISA bridge: Intel Corporation 82801FBM (ICH6M) LPC Interface Bridge (rev 03)
00:1f.1 IDE interface: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) IDE Controller (rev 03)
00:1f.3 SMBus: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) SMBus Controller (rev 03)

I tried adding "options libata noacpi=1" to /etc/modprobe.d/options.conf (per some discussion in the forums) but it did not resolve the issue.

Let me know if further data would be helpful.
