Bug#600305: Clarifications on this bug
In order to clarify the new goal of this bug I am making a note to help
the maintainer of this package.
The chipset MCP89 manufactured by Apple in their 2010s laptops and
designed by nvidia was not properly recognized by the current squeeze
kernel, resulting in failure to detect any ata devices on the system.
Models using MCP89:
Macbook 6,1
Macbook Pro 7,1
Macbook Air 3,1
Macbook Air 3,2 and maybe others, especially in the future.
Hence, upstream kernel developers created patches using the module
ata_generic to detect the devices, then force them to support DMA.
Debian kernel maintainers applied this two patch to the current kernel
successfully
([http://packages.debian.org/changelogs/pool/main/l/linux-2.6/linux-2.6_2.6.32-28/changelog|since
2.6.32-27]).
However D-I installation process involves kernel-wedge and
linux-kernel-di. They do not allow the detection of the ata devices at
the moment. This result to the impossibility in installing debian using
the net-install CD.
[http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=605325|Bug#605325]
include a patch that add ata_generic detection to kernel-wedge.
Cheers,
Mathieu.
