When you boot, and it pauses, use the up and down arrows to choose advanced options. Choose your old kernel. And boot. Delete the new one with the software manager. You shouldn't be locked out.

Eventually the fans stop and the system sits idle with no video output. I updated the kernel using the system update tool. This system is down stream on Mint, so I can't use the instructions as written in the submission form. But I will do my best. I had to roll back to -157 to write this report. Hope this helps.
