These are not really failures, just warnings.
All of the Linux memory management APIs have not been implemented and
the radeon driver is unhappy about it but that doesn't prevent things
from working.

Unfortunately, it's hard to find out what is going wrong here.

There is a new version of the radeon driver (and drm code) in the
branch drm_ttm_radeon_4_9_rebased in my repository on leaf, which
will likely be pushed soon to master. It could perhaps help.

You could also try disabling OpenGL usage in chromium:

  chrome --disable-gpu

ATB,
