From dedc14e2a6e85b357c2274e03af354201e0b5626 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Fri, 1 Jun 2012 11:11:09 +0100 Subject: drm/cirrus: kick out conflicting framebuffers earlier It appears that grub2 will pass framebuffer info via EFI, this causes the vram reserve to fail, so kick out efifb earlier before cirrus loads.
