Freeze on map mode

[Bolche]

I had this issue since .90 came out. Sometimes, usually in map mode, the game would freeze for a minute or so and them come back.

I finally solved it and I'm here to help someone else that might be having this issue.

It's systemd's fault (or the radeon driver not getting along with systemd or something like that) . Basically when the GPU does some activity (I suspect it's fence signaling, but can't say for sure), it causes journald to create a coredump and spend a long time dumping the process to the disk.

You can solve it adding

Storage=none

to /etc/systemd/coredump.conf

I'm on Archlinux x86_64 with intel/radeon open source drivers.

I hope it helps someone.
