In total it is 198 seconds that are lost in these timeouts during boot, more than 3 minutes! Regression is present since linux kernel 4.8 (with Ubuntu 16.04). To fix, explicitly disable the port with an i915 module setting with video=SVIDEO-1:d in the kernel command line parameter in the bootloader. 1/ sudo gedit /etc/default/grub 2/ add "video=SVIDEO-1:d" to "GRUB_CMDLINE_LINUX_DEFAULT" line 3/ sudo update-grub After applying this, the system boots up much faster, there are no "drm ... timed out" messages.
