binding. (b0f1767d776e2c80cab4343b4cd59553fbf5e48a)

this path doen't fix the problem sorry.
but i have note that I have the problem with kernel 3.6.39.1, but I haven't the
problem with kernel 3.0-rc4.

It seem to be fixed by kernel 3.0.
Peraps a modification in drm need to be merged in 2.6.39 branch.

Peraps, but i probably need help.
I don't know how bissect only drm patch, because bissect all patch on kernel
3.0 seems to be very long.

And I need to find how package kernel without rebuild all.
For now when i build a kernel, i launch a command who make the build and the
packaging. But this command rebuild all each time.

peraps it have sense to push this patch in branch 2.6.39

At the beginning of bisect, display lock during the first piglit test.
But in a second part, display lock only in the second test, when chromium is
launch (with some opened page).

Unfortunately that patch is not related to your chip at all (there are no
redwoods with dp bridge chips).  I think it's a false positive.
