After disabling plymouth-splash I can't reproduce this anymore.

It's a race between plymouth and xorg. Plymouth holds DRM master (drm_setmaster_ioctl) while xorg tries to start (drm_setversion) and fails with EACCESS because it needs DRM_MASTER for that.

It works fine if
1. plymouth never starts
2. plymouth calls drm_dropmaster_ioctl before X starts

And another thing is the Xorg.log timestamps can't really be trusted.
