Hello,

Sorry if I'm posting this wrong, but I get the same error, using Linux Mint kernel version 5.4.0-137 on HP Elitebook 745
I installed the latest: 5.4.0-144 and the issue still persists. 
It's not only that the messages appear on the console, but actually takes several restarts (using the button) to load the system.
