--- Comment #1 from Tom Seewald <tseewald at gmail.com> ---
This bug report on the kernel bugtracker appears to be the same or at least a
very similar problem:
https://bugzilla.kernel.org/show_bug.cgi?id=204181

In that report, Nicholas Kazlauskas posted a possible fix:
https://patchwork.freedesktop.org/series/64505/

I have yet to test to see if this patch resolves the crashes I am experiencing,
but I don't see this as being in the 5.3-rc series, and certainly not in the
5.2 stable releases. Was this fix perhaps overlooked/missed?

So far I just see that it is in amd-staging-drm-next as of August 1st:
