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].

Keyboard works to unlock encrypted harddrive before that though. If I plug in a USB keyboard or activate my bluetooth mouse, I can use those to log in, and then after logging in the laptop touchpad and keyboard work again. Logging out of the desktop results in the laptop touchpad and keyboard working on the gdm screen. Did not see this behavior before upgrading from 1.2.0 bios to 1.4.0 bios, but also had not rebooted in a while, so not sure if bios or package upgrades triggered this behavior.
