This seems suspicious. Can you be sure that kernel-devel was installed properly
in this machine? We have landed a patch to skip building the tests if
kernel-devel is not installed. We check if /lib/modules/<kernel-version/build
is present to start building, but I would expect Module.symvers to be present.

Please let me know if we need to adapt our tests further to avoid such problems.

Sorry, this is another problem due to the different way of organizing
the files at the bot side. We are looking into this to put the required
materials to the correct path. This report should be a false positive,
please ignore it.
