--- Comment #7 from Chris Rankin rankincj@googlemail.com --- FWIW, my nephew has played TF2 (Steam's "Team Fortress 2", presumably) for HOURS recently with HD 6450 and recent Mesa 12.1.0-devel.
If it had locked up even once then I would have known about it... ;-).
The base OS was Fedora 24/x86_64 with LLVM 3.8.0.
