From 71508e151a64de75bfdef4e83b8059a01e25a589 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Fri, 14 Nov 2014 10:09:49 +0100 Subject: [PATCH] drm/i915: Kick fbdev before vgacon commit 0485c9dc24ec0939b42ca5104c0373297506b555 upstream. It's magic, but it seems to work. This fixes a regression introduced in commit 1bb9e632a0aeee1121e652ee4dc80e5e6f14bcd2 Author: Daniel Vetter Date: Tue Jul 8 10:02:43 2014 +0200 drm/i915: Only unbind vgacon, not other console drivers My best guess is that the vga fbdev driver falls over if we rip out parts of vgacon. Hooray.
