title="NEEDINFO - i915 triggering ACPI GPE storm"
href="show_bug.cgi?id=90014">https://bugs.freedesktop.org/show_bug.cgi?id=90014</a>
I need to patch my kernel to actually be able to use the integrated GPU, as
otherwise the EFI firmware turns it off (see
<a href="http://lists.gnu.org/archive/html/grub-devel/2014-11/msg00034.html">http://lists.gnu.org/archive/html/grub-devel/2014-11/msg00034.html</a>).
With the IGD activated and the i915 driver loaded, there is one kworker using
one core at 70% all the time, and acpi/interrupts/gpe06 growing continuously
increasing. With the IGD activated but i915 has not been loaded, then gpe06
remains at 0 interrupts and there are no kworker using more than 5%.</pre>
