It appears that the culprit is an old or broken libvulkan_radeon.so provided by mesa-vulkan-drivers. As a test I renamed the old lib and dropped in a newer version from oibaf's ppa. smoketest now passes steam's The Talos Princible and Mad Max now work properly in Vulkan mode as well instead of segfaulting. This issue is also present on Zesty and fixed in both Oibaf's and Padoka's ppa's since April back when they were rolling 17.2 mesa. I have no idea if libvulkan_intel.so also needs updating no hardware to check.
