full dmesg during boot

Hi,

On a HP EliteBook 840 with a Intel HD 4400, the VGA output only works once.

Steps to reproduce:
1. boot
2. plug a project to the VGA output => works fine
3. unplug it
4. plug it again => doesn't work (shown as disconnected in xrandr)

Software versions & hardware:
Linux grr 3.18.0-trunk-amd64 #1 SMP Debian 3.18-1~exp1 (2014-12-11) x86_64
GNU/Linux

$ pkg-config --modversion libdrm ==> 2.4.58

(II) Module intel: vendor="X.Org Foundation"
     compiled for 1.16.2.901, module version = 2.99.917
(--) intel(0): Integrated Graphics Chipset: Intel(R) HD Graphics 4400

Thanks!
