From what I can piece together without using a serial console and

capturing from another host:

[1.923827] Kernel panic - not syncing

Samuel might be able to decipher this, but I have an off the wall idea.
Kernels get bigger with each release.  I wonder if there is a memory
problem, that the earlier kernels don't trigger, but the larger kernels
do.  Run a memory test?

The other thing to try is re-installing the kernel.  A really long
shot, but worth a try.

And maybe it is a kernel bug.  The line you are referring to is
   VM_BUG_ON_PAGE(bad_range(zone, page), page);
and it occurs when trying to deallocate a page.

static inline void __free_one_page(struct page *page,
       unsigned long pfn,
       struct zone *zone, unsigned int order,
       int migratetype)
{

I interpret the errors as saying that the kernel is trying to
deallocate a page, and the CPU receives a 0000 opcode.  That would be
an error.  But is it coming from the kernel, or is the kernel reading a
bad location?

I think it has to be something about your hardware, because if the
kernel was actually having trouble deallocating pages for all boots,
this would be a well known problem.  Maybe you have hit a corner case.
You could open a bugzilla, but it will be difficult for someone to fix
this without your hardware to replicate the crash or the complete crash
output.

The 4.20 kernel series is not far away from coming to stable.  You
could either grab one from koji,
https://koji.fedoraproject.org/koji/packageinfo?packageID=8
or use an older kernel until it is released.  It might fix the issue as
a side effect of other changes.
