[Libreboot-dev] i915 GPU hang (release 20141015 - X60S)

[Robert Alessi]

Hi,

As I have time at present, I am in the process of updating Libreboot
in order to be able to reinstall Parabola of a new fully encrypted HD.

With release 20141015 new error messages appear at boot time:

But I suppose it's nothing to worry about: the first message complains
of i915 being absent in ROM, which is just the case since I do not
have a BIOS.

Am I right?
