That's the one. `git branch` returns drm-tip.

When I run a script that makes bzImage and modules and then tries to
install, I get multiple errors to the effect that the modules to be
installed cannot be found:

On the other hand, when I run `make bzImage modules` it stops abruptly
with the two lines I sent. Here's the final segment I can see on the
screen:
