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

[Stefan Bader]

The changes have been accepted into upstream as of today and should
automatically get picked up by Maverick.

** Also affects: linux (Ubuntu Lucid)
   Importance: Undecided
       Status: New

** Changed in: linux (Ubuntu Lucid)
   Importance: Undecided => High

** Changed in: linux (Ubuntu Lucid)
       Status: New => In Progress

** Changed in: linux (Ubuntu Lucid)
       Status: In Progress => Fix Committed

** Description changed:

+ SRU Justification:
+ 
+ Impact: SATA drives on the MBP 7.1 are not usable as the ahci mode is
+ not working correctly.
+ 
+ Fix: Two patches taken from upstream, which have also been marked for
+ stable inclusion will blacklist the MBP from using AHCI and falling back
+ to the ide driver which works. Second half forces DMA on.
+ 
+ Testcase: See report. Disk drive not usable without the patches.

  Booting 10.04 livecd on one of the new MacBook Pro(7,1) results in SATA
  drives not being detected, and thus, not being able to install 10.04.
  
  The new MacBook Pro has the MCP89 chipset.
