--- Comment #3 from Michael J Evans <mjevans1983 at gmail.com> ---
After looking at the linked bug and your description of my environment (dual
screen and yes KDE / Plasma as a compositor potentially exposing whatever
corner case this is in the kernel driver):

I agree this is likely a duplicate of that issue.

The above dmesg contained the only relevant data post-boot, though if you'd
like sections of specific drivers initializing other other memory data I can
provide a more hand-picked selection of data for the next crash.

After this evening's crash I've updated to the latest arch-linux kernel and
packages.

The kernel is now booting with a 'cmdline' including: amdgpu.gpu_recovery=1
log_buf_len=64M drm.debug=84 debug

I've kept my desktop environment the same in the hope that I might collect a
useful crash context with the added data.
