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: https://cgit.freedesktop.org/~agd5f/linux/commit/?h=amd-staging-drm-next&id=a4f6a4c7de97335f3452229e67521eae338af10e
