[Bug 576601] Re: [MacBookPro 7, 1]mcp89 sata link reset fails, no disks detected

[Eric Garrido]

The current status is that:

1) There exists an experimental/development ISO that allows
installation, albeit using the ata_generic driver. This means accessing
disk without AHCI and without DMA.

2) There exist experimental/development kernel packages that are in
-proposed (or so says an above comment) that enable DMA. I've been
running all weekend with these packages with no issues. The applied
patches are being merged upstream "soonish".

3) The AHCI driver is reported to work when using grub-efi, but then the
nvidia driver breaks. In non-EFI mode, the nvidia driver works (but
obviously AHCI does not work).

4) It's unknown if there will ever be AHCI support with non-EFI, or
nvidia support in EFI, as it's not clear what makes these break yet.

The work around is good enough for my own *personal* use for now (YMMV).
Is it worth opening new bugs for fixing #4 or is it too much of a pipe
dream (especially seeing as how 4b is a binary, proprietary driver)?
