From 6147ba0e962c3d7ba28b53b9b930f1bed5833c90 Mon Sep 17 00:00:00 2001 From: Darren Hart Date: Tue, 23 Apr 2013 14:32:19 -0700 Subject: fri2: Disable MSI interrupts for the HDA device Fixes [YOCTO 3814] MSI interrupts fail when using the EFI firmware on the FRI2. Disabling them enables the HDA device to function properly on both BIOS and EFI versions of the device.
