I can confirm I have encountered this issue with BIOS v. 1.6.1 from 21 Jul 2019
Device - Dell XPS 15 9575 Intel Core i7-8705G BIOS - version 1.6.1 OS - Fedora 30 Kernel - kernel-5.1.19-300 Additional info: - I have an encrypted root partition. During boot, I am able to usethe keyboard for <1 second at the screen where I enter the password for the root partition. Then the keyboard is disabled. - I tested this with a previously installed kernel 5.0.9-301 and I was able to use the keyboard to enter the password for the root partition, but once I arrive at the login screen for fedora the keyboard/touchpad is unusable (cannot even switch TTYs) - Using the grub boot menu option "fedora rescue" which is installed by default with fedora, I am able to use the keyboard to login without issue. I'm happy to share any additional information that is requested. I don't see any specific errors in dmesg that stand out here, but I've provided a dmesg from a boot when the keyboard would not function [0]. I will also upload a dmesg from a functional boot[1].
