Oops, it turns out the problem was actually occurring during "make modules" not "make modules_install". I'm calling kbuild through some autoconf generated Makefiles, and autoconf always wants the "install" target to depend on the "all" target. This results in the kernel's "make modules" getting re-run as root before "make modules_install". This fails due to the .tmp_versions and similar getting unconditionally rebuilt during "make modules" (output attached). I've worked around it by having the autoconf make all target ignore errors from the invocation of the kernel's "make modules". -- Frank
