I've done some digging:
/lib/modules/188.8.131.52-31-rt/build is a symlink to
This directory contains only a single file called Module.symvers (matching

I've gone back to the updated kernel, and successfully re-installed the NVidia
driver - so I evidently have correctly configured sources. Looking at
/usr/src/linux-184.108.40.206-31-obj/x86_64, there are directories for default, xen
and debug, and they each contain version.h - but there is no rt/ folder.
I'm not a coder, so all I have to go on is logic - but it appears to me that
the kernel-source package does not include the necessary files for a realtime
Is there any way that these files can be generated without rebuilding the
