Working with Pirouette on IRC, we determined this may be related to https://bugzilla.kernel.org/show_bug.cgi?id=201957#c94 in which the solution, sadly, was to add amdgpu.mcbp=0 to the kernel boot parameters. Per that bug report, it does appear as though this might be the result of a regression in the 6.5 kernel as they did not experience this issue in prior kernels or Ubuntu 23.04.

They also found mentions of https://gitlab.freedesktop.org/drm/amd/-/issues/2848 where Kernel 6.6 has a fix which we could pull a patch from, and we might have a patch for mesa at https://gitlab.freedesktop.org/drm/amd/-/issues/2848#note_2095536.
