With my ICH8m, sorry it took so long, was on a holiday. I wrote it down, but I think it is correct. Hope this helps. For anyone without a serial port, apply the patch from bug 1444, to scroll debug output, one page at a time (press enter for next)

This ticket is 9 years old. AHCI has changed a lot since then. Please re-open if the issue still exists on the same hardware device.
