From c6353b4520788e34098bbf61c73fb9618ca7fdd6 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 17 Jun 2010 11:42:22 +0200 Subject: ahci,ata_generic: let ata_generic handle new MBP w/ MCP89 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For yet unknown reason, MCP89 on MBP 7,1 doesn't work w/ ahci under linux but the controller doesn't require explicit mode setting and works fine with ata_generic. Make ahci ignore the controller on MBP 7,1 and let ata_generic take it for now. Reported in bko#15923. https://bugzilla.kernel.org/show_bug.cgi?id=15923 NVIDIA is investigating why ahci mode doesn't work.
