FYI, the latest stable Linux release (4.17.7) is not suitable
for i386
(i686-linux) systems. Quoting Greg Kroah-Hartman:
"NOTE, this kernel release is broken for i386 systems. If you
are
running such a machine, do NOT update to this release, you will
not be
able to boot properly.
I did this release anyway with this known problem as there is a
fix in
here for x86-64 systems that was nasty to track down and was
affecting
people. Given that the huge majority of systems are NOT i386, I
felt
this was a safe release to do at this point in time."

So, we should take care to preserve the linux-libre 4.17.6
package
definition for i686-linux, or skip this release.
