I think I've found the commit that actually fixes this. The patches and bug reports were leading me to believe this was a bug entirely in the ahci driver, but in fact, it's a combination of that and the IDE layer.
I've cherry-picked some patches out of 2.6.18 that should resolve the problem. I'm upload kernel source today, which should build by the end of the day, and there should be new daily ISO's tomorrow with this kernel on it. -- JMicron PATA/SATA Controller does not work https://launchpad.net/bugs/57502 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
