Bug Description
== SRU Justification ==
[Impact]
Wobbly graphics after a kernel update.
[Fix]
Older panels may require more bandwidth then advertised, so we need to
use max params for them.
[Test]
Multiple users tested with positive result.
[Where problems could occur]
This patch reverts to the old behavior, which is to use max parameters,
for older panels. If there's any new panel reports with older DP
version, this might change the behavior on it.
== Original Bug Report ==
Lenovo laptop with Intel + Nvidia graphics.
Since booting from linux-image-

HDMI output works fine.
If I boot from linux-image-
If I use Recovery mode with linux-image-
