--- Comment #7 from Jean Hertel <jean.hertel at hotmail.com> ---
I made some additional debugging and found so far that when I run with
EGL_PLATFORM=drm mesa loads by default /dev/dri/card0.
When the driver tries to ioctl it to get additional data (on
src/intel/dev/gen_device_info.c:1349), it receives a EACCES error, indicating
that something is missing.

If I hard-code on mesa to load /dev/dri/renderD128 I receive a ENOENT error. So
I'm kinda lost of what could be wrong here. Maybe MESA opens the driver
incorrectly? Or is this a i965 bug?
