As it seems this problem comes from the CRT hotplug detection.
I have booted the kernel with this option "drm.debug=0x06" and now I see this message in my logs:
kernel: [ 833.140022] [drm:intel_crt_detect], CRT not detected via hotplug

As a workaround I have tried to execut this command:
echo N > /sys/module/drm_kms_helper/parameters/poll

but this didn't help. It had no effect the message was still in my logs.
I also asked on irc #intel-gfx for help but got no answer so far.
