I just submitted this redhat bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1528754, but I see the ir-keytable man page says send bug reports here, so here I am :-).
When I updated my Intel NUC recently with latest fedora 26 updates, I got a 4.14 kernel and the next time I tried to use kodi after that, all my remote key presses were duplicated. I went back to the previous kernel (4.13) and everything worked fine. More details can be found in the bugzilla linked above.
