--- Comment #2 from Sylvain BERTRAND <sylvain.bertrand at gmail.com> ---
I did a lot of testing and dumped cores (libsegfault.so or catchsegv do not
work with steam/dota2), the issue is actually random: sometimes it works, most
of the time it crashes or hangs the vulkan dota2 process or hangs the whole
system. Using the steam overlay with vulkan dota2 makes the crashes/hangs do
happen way more often. The segfault backtraces happen in various parts of
vulkan dota2 (I got very few of them in mesa vulkan driver) and do not show
anything in libdrm*. I even did manage to crash the new steam chat (it was
unable to restart itself). If I read a video (gl accelerated) at the same time,
it changes the way vulkan dota2 crashes/hangs.

The system is stable again if I switch back to the previous libdrm hash table
code.
