GALLIUM_DDEBUG dumps during the GPU freeze

I run TW3 with GALLIUM_DDEBUG=10000 (10 second delay for GPU hang detection).
It detected the hang when it actually happened (I also had to build umr
debugger from source, since Mesa complained otherwise that umr isn't found).

I attach produced dumps, please check if it helps identifying the issue. See
also included debug.log for console output. Let me know if it can be run in
some other way to get more information.
