Title:
"drm timed out" with driver i915 + Intel Mobile GM965/GL960 Integrated
Graphics with Kernel 4.15
Status in linux package in Ubuntu:
Confirmed
Bug description:
With Ubuntu 18.04 + Kernel 4.15, at boot time there are many periods when the
boot freezes before the timeout of 10 seconds with Intel Mobile GM965/GL960
Integrated Graphics (driver i915).
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.
