<pre>I've been bisecting and it appears that there are at least 2 further
regressions...
At one point in the bisection, the display goes from working to visible, but
with what look like hsync problems. I can see all the lines on the display, but
each line is shifting horizontally by about 16 pixels or so - giving a
shifting, fuzzy picture.
I've pinned this problem down to the following commit:
486a45c2 drm/nouveau/i2c: do parsing of i2c-related vbios info in
nouveau_i2c.c
There are no differences in the console output between this commit and its
working parent commit.
Much later in the bisection, this hsync problem is replaced with the
fade-to-black problem I described before. I haven't finished bisecting this
yet, but will continue.
Chris.</pre>
