@velartrill Not sure if you still need it, but here are my laptop & server, both running Gentoo:
Linux whumass 5.4.28-gentoo #1 SMP Tue Apr 28 13:47:05 CEST 2020 x86_64 Intel(R) Core(TM) i5-6300HQ CPU @ 2.30GHz GenuineIntel GNU/Linux
Linux wuatek 4.19.97-gentoo #1 SMP Wed Feb 12 19:01:27 CET 2020 x86_64 Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz GenuineIntel GNU/Linux
Huh, I haven't rebooted the server after the kernel update, should probably do that...
