Dave, you mentioned that you were going to pull in the TTM Kconfig fix
that I submitted (the one that allows TTM to be built into the kernel
instead of just a module). What are you going to do about the hardlock
that occurs when drm/radeon/fbcon are all built into the kernel. It
seems like fbcon does not get initialized before radeon and as a
result, there is a hardlock. My fix was to init radeon later which
works fine for me. Maybe it would be better to init fbcon earlier if
possible? Either way, I am not sure if you missed that patch so I am
going to resubmit it here as a reminder that this bug exists if you
build everything into the kernel..
