--- Comment #39 from Jérémy Lal kapouer@melix.org 2011-05-08 15:39:33 PDT --- Created an attachment (id=46455) --> (https://bugs.freedesktop.org/attachment.cgi?id=46455) efi iMac12,2 dmesg

Same problem with latest iMac12,2 (27") when booting with efi. (I had to patch kernel 2.6.38 because of https://bugzilla.kernel.org/show_bug.cgi?id=23202)

The first attachment is booting with efi, the second booting with bios. I removed the timestamps from mesg to ease the diff.

EFI : black screen when drm is activated (not before) BIOS : drm and Xorg work, DRI2 activated.
