BIOS installed and an internal Intel Wireless 8265 / 8275 adapter:

Title:
Intel WiFi AX200 [8086:08b1] subsystem [8086:4070] firmware loading
error resulting in no wifi
Status in Gaming Edition:
In Progress
Status in linux-firmware package in Ubuntu:
Confirmed
Bug description:
Ubuntu 19.10 - stock kernel - Intel AX200 PCI card in a desktop PC
uname -a
Linux nahuatl 5.3.0-18-generic #19-Ubuntu SMP Tue Oct 8 20:14:06 UTC 2019
x86_64 x86_64 x86_64 GNU/Linux
The card is detected OK as dmesg shows, however the card's firmware
fails immediately after loading (see dmesg output below) and wifi
doesn't work at all. Big disappointment since the AX200 chip was
supposed to be supported on 19.10.
Ubuntu includes two ax200 firmware versions, version 48 loads by
default in my system (and fails). I tried version 46 (by renaming the
version 48 file) and it failed in the exact same manner
$ ls /lib/firmware/iwlwifi-cc-*
/lib/firmware/iwlwifi-cc-a0-46.ucode /lib/firmware/iwlwifi-cc-a0-48.ucode
The card's Bluetooth functionality is also detected and it works fine. It's
just the wifi FW loading what seems broken in ubuntu's 5.3 kernel.
$ rfkill list
0: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no
