In the Total War: Warhammer campaign mode, leaving the game running for a long time while showing the campaign map can result in a hang when using an AMD Rx 480. It can take an hour or more to reproduce.

When the hang occurs, the entire system becomes unresponsive, so I am unable to gather any information about its state over ssh for example. As I can't diagnose what happened after the event, or practically step through what goes on immediately before it, I'm out of ideas for debugging it, so any advice would be appreciated.

Seen in Mesa 13.0.1, and git b18cd8c, 0f2e9a8, and cb6f49a on Ubuntu. We also tried leaving a machine with an R9 290 running overnight, but that had not reproduced the hang by the following morning.

Steps to reproduce: 1) Place the attached save game file in path ~/.local/share/feral-interactive/Total War Warhammer/VFS/User/AppData/Roaming/The Creative Assembly/Warhammer/save_games/dwarfs 73.save 2) Launch Total War: Warhammer from the Steam client 3) On the main menu, select Campaigns 4) Select Load Campaign 5) Select Load 6) Leave until display freezes (we've seen it take about an hour, but we typically leave it overnight and find it hung in the morning).
