В testing'е Slackware-current обновили и пропатчили ядро, и, судя по комментарию, результат получился неплохим. Так что, есть все шансы на возвращение ядра 4.14 из testing'а обратно в основную ветку.
These sources have been patched with two patches that have been submitted upstream but have yet to appear in the mainline or stable kernels. With the patches applied this kernel seems stable now on both 32 and 64-bit x86. Thanks to Michele Ballabio for reporting the issue to the upstream kernel developers, and to Ming Lei for the fix. Once these patches appear in the 4.14.x kernel series (and barring any other major regressions), we'll be moving these kernels back into the main tree.
