Title:
i915 kernel module loads 1 cpu core 100%
Status in linux package in Ubuntu:
Confirmed
Bug description:
When no display is connected to the HDMI port of the integrated
graphics card (i915), one core will go to 100% load until a display is
plugged in again.
For a headless system the workaround is to blacklist the i915 module
in grub.
There are several patches around:
https://bugs.freedesktop.org/attachment.cgi?id=145826
https://github.com/torvalds/linux/commit/67322bec979caa33e0ac4505306bf70af46208e4
maybe a backport of one of these patches to the current kernel would
be an option?
