T470s - How to prevent screen blanking during suspend

My running well T470s Thinkpad starting having kernel panics during suspend when kernel 4.19 showed up and has continued through kernel 4.20.
I froze working kernel at 4.18.19-1-ck and it's great. I finally found some time to try and get to the bottom of the panic today. Many many reboots later and every kernel param I could find has shown me nothing!

Anyway, there is a message flashed when suspend is issued using systemctl suspend but the screen blanks before I can read it.

Anyone know how to capture that output or prevent the screen from blanking?
