--- Comment #17 from Michael ZeroBeat@gmx.de --- It is possible, that the original issue isn't reproduceable any longer, because of several updates in the meantime. Also it's possible that the issue is related to Arch linux. But I don't think so, because 4.5 is running fine on 4 different systems [different kernel versions, different CPUs (AMD, INTEL), different drivers (nouveau and nvidia)]. I'll try to get the corresponding WINEDUBUG log for the initial crash.
