I had the same problem on my T61. I initially changed the SATA config in the BIOS to "compatibility" as a workaround.

Then I found this other bug

  https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/162536

where it says it's actually a BIOS problem.

So I did the BIOS upgrade (and a drive firmware upgrade as well for good measure), set SATA mode back to "AHCPI" and now it seems to be working fine.
