[Bug 575985] [NEW] kernel: [...] i915 0000:00:02.0: LVDS-1: EDID invalid.

Public bug reported:

During boot my screen goes blank. Instead of a normal plymouth screen I
see something like this:

[drm:edid_is_valid] *ERROR* Raw EDID
[drm:edid_is_valid] *ERROR* Raw EDID
[drm:edid_is_valid] *ERROR* Raw EDID

this might be a problem with intel's i915 chipset. This bug comes new
with 10.04 - it never appeared with ubuntu 9.10.
