Hi folks,

I have a Dell e6410 whose framebuffer gets corrupted with v3.7.9 and
v3.8.0 but works fine with v3.6.11.

Below you can find lspci and my .config, maybe I'm missing something ?

You don't describe how the fb gets corrupted, so it is impossible to
guess the likely cause. When in doubt, please attach a photograph of
the corruption.
