Public bug reported: At boot time there are many periods when the boot freezes before the timeout of 10 seconds. 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. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: gm965 i915 ** Attachment added: "dmesg Ubuntu 18.04 with Intel Mobile GM965/GL960 Integrated Graphics" https://bugs.launchpad.net/bugs/1767808/+attachment/5130165/+files/201804_ubuntu1804_kernel_4.15.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1767808 Title: "drm timed out" with driver i915 + Intel Mobile GM965/GL960 Integrated Graphics with Kernel 4.15 Status in linux package in Ubuntu: New Bug description: At boot time there are many periods when the boot freezes before the timeout of 10 seconds.
