It might be useful to see what the Intel and/or r600 series drivers do as
neither of these driver exhibit this crash in similar circumstances. The Intel
Mesa driver might be best as this driver was fully supported from release
without any reports of hangs post release. It's possible a comparison might
help expose why RadeonSi behaves differently and narrow down the cause of the
hang as it could be the root cause is hiding behind a more benign issue.
