The latest dota2 builds, on an up-to-date fedora rawhide, do crash after playing or watching a game for a little while (I tried previous mesa versions (down to first 10.0) with a fedora contributor, still crashing). I reproduced the crash with a radeon evergreen (juniper) and a radeon southern islands (tahiti). relevant dmesg output: [ 239.027439] dota_linux[1345]: segfault at 0 ip 00000000f23f1eeb sp 00000000ffb402d0 error 6 in engine.so[f1e15000+b52000]
And it does not crash with the close source driver on steamos.
the b52000 offset is the same of both GPUs.

Yes... it's that bug. Then it does not seem related to the radeon open source driver. How did you manage to get the symbols?
