Game freezes after a minute or two for about a minute. It is then very likely to disconnect (about 3/4 of the time), although if it does not it will play fine after the freeze.

However, the fix listed here fixed it - sudo sysctl kernel.split_lock_mitigate=0. Keep in mind, that only changes the setting for that session. To make the change persistent, add the following line to /etc/sysctl.d/99-splitlock.conf: kernel.split_lock_mitigate=0.

In my case, it stops it from both freezing and disconnecting. Some here have reported that it only keeps them from disconnecting, so ymmv.
