Ok, thanks for the update. Interestingly, AFAIK the iwlwifi driver
specifies a max API number (50 in case of the focal 5.4 kernel) and
tries to load that firmware and then walks down until it succeeds:
[ 9.458673] iwlwifi 0000:52:00.0: Direct firmware load for
iwlwifi-cc-a0-50.ucode failed with error -2
[ 9.458850] iwlwifi 0000:52:00.0: Direct firmware load for
iwlwifi-cc-a0-49.ucode failed with error -2
[ 9.462480] iwlwifi 0000:52:00.0: loaded firmware version 48.4fa0041f.0
op_mode iwlmvm
So the driver loaded iwlwifi-cc-a0-48.ucode and I'm surprised that
replacing -46.ucode made a difference for you.
Anyways, I'll close the ticket. If you come across this problem again,
please open a new ticket.

Title:
enabling wifi crashes thinkpad x1 extreme (gen2)
Status in linux-firmware package in Ubuntu:
Invalid
Bug description:
On enabling the wifi interface, the laptop crashes (lockup, without
further error messages) soon thereafter (10-20s)
Fix is to replace /lib/firmware/iwlwifi-cc-a0-46.ucode with the
corresponding file from
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi
# - download archive for AX200:
cd /tmp
curl -O
https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi/iwlwifi-cc-46.3cfab8da.0.tgz
# - extract
tar xvzf iwlwifi-cc-46.3cfab8da.0.tgz
# - copy firmware
cp iwlwifi-cc-46.3cfab8da.0/iwlwifi-cc-a0-46.ucode /lib/firmware/
My laptop is as follows:
