Сабж. В Changelog'е внезапно появилось это:
We're moving back to the 4.9.x kernel series in the main tree until we can figure out a fix for unstable 4.14.x kernels (especially on 32-bit). Guessing it's probably going to be fixable with .config changes, since a greatly simplified .config is stable. Meanwhile, the latest 4.14.x kernels can now be found in the testing/ directory.
И, да, ядро 4.14 теперь в testing'е, а в -current вернулось ядро 4.9:
a/kernel-generic-4.9.66-x86_64-1.txz: Upgraded.
a/kernel-huge-4.9.66-x86_64-1.txz: Upgraded.
a/kernel-modules-4.9.66-x86_64-1.txz: Upgraded.
