I was able to get an external USB/SATA bridge and used it on the same HDD that I have been testing with. With that setup I was able to boot Karmic all the way.

Then after some more fiddling, I made a cable to only use the data path of the Babbage USB/SATA bridge, but used an external power source. This configuration failed.

Then I used the power from Babbage SATA connector to power up the SATA HDD, and used an external USB/SATA bridge, this method was OK in booting up Karmic.

These experiments hints that perhaps the Babbage USB/SATA bridge is not stable under this new Ubuntu version. Perhaps there are power glitches with the power to the SATA bridge? Perhaps timing violations with the bridge chip that is exposed in this version of Ubuntu that weren't there before.

We have engaged the manufacturer of the USB/SATA bridge to help with debugging this issue.
