Comment 58 for bug 1942684

Had a similar issue on a 20.04 install today after updating to 5.14.

Woke it up from suspend on 5.10.0-1057-oem. Rebooted once (some screen issues that turned out to be the screen), installed updates via update-manager, rebooted using the new 5.14.0-1024-oem kernel and it just hung. Black screen, blinking cursor.

I noticed that the lenovo splash screen did not come up after selecting the 5.14 kernel in grub. It does with 5.10.

Going back to 5.10 works as before. I have a kern.log saved from the before and after the update, but do I need to make sure it is sanitized for secure boot keys and such?

Also, it should be noted that it is a dual GPU system with an intel and nvidia.
