I think I see the same bug on Dell Inc. Latitude 7390 2-in-1/0YNG30,
BIOS 1.10.0 07/04/2019
Distributor ID: Pop
Description:Pop!_OS 20.04 LTS
Release:20.04
Codename: focal
Observed on the latest four kernel versions:
vmlinuz-5.4.0-7618-generic
vmlinuz-5.4.0-7629-generic
Exactly the same problem but my log files are very big (almost 1To and crashing
my computer).
I am on a Lenovo Yoga 14ARR (with a Ryzen 5) on Ubuntu 20.04LTS.

Failed check-sdata-in-driver check, flags: 0x4

Also began happening for me, starting a week ago (but no apparent
cause). Ubuntu 20.04, 5.4.0-42-generic, Intel NUC. Same symptom of
wildly scrolling kernel log, eventually fills the disk.

These are the part before the start of the error dump looping. One of
the lines is giving a 'Microcode SW error'. Is this the cause

Similar error. Syslog grew to 11GB and I see the repitition of this
error message seemingly from the mac80211 driver. The error message (in
syslog) below repeats forever and fills up syslog. I don't know exactly
what triggers it.

Title:
Intel 3945ABG [8086:4227] Subsystem [8086:1010]: syslog flooded with
"wlan0: Failed
There are reports that QCA6174 may trigger warnings by turning off WiFi,
and I'm recently able to reproduce that with an Intel 9260 by a wifi-
onoff stress script.
