Description

In 4.1.5, loading Nouveau results in an "Unable to handle kernel paging request in evo_wait, which is called from nv50_display_flip_next. Last time I tested in 3.18.0 (at commit d1b8792), it didn't happened. I'll try to bisect it and get some more debug information.

The bug happens only when I force POST using config=NvForcePost=1. If I remove it, everything is fine.
Except if I put the G84 as a secondary GPU: see this bug report.
