Public bug reported:

Two-three months ago, I started having this kernel bug.

When I boot using kernel 46, "linux-image-4.15.0-46-generic" everything
seems to be functional.

But when I boot using one of the more recent kernels, the system usually
crashes or reboots. I have noticed the problem on 51,52,54,55,58 so far.

I have taken pictures of the loop (attachments), this is a transcript of the 
bug:
