Description Sylvain BERTRAND 2019-11-08 17:34:37 UTC
games started to randomly crash, vulkan or GL (dota2, dota2 underlord, CS:GO). The only info I get from the crashes, are from dota2 vulkan (see kernel log) and dota underlords. This is a mesa vulkan debug build and the offset 0x1e08000 does not map to any source code (glibc addr2line). I cannot bisect correctly since some sessions have no crash at all for hours. Any ideas? (for the moment, I can update linux/drm/llvm/mesa/xserver every week)

Probably a mesa bug rather than a kernel bug.

ok, seems I got it: was weird I got no debug infos with a constant crash location in a debug build... because the crash was... in c++ cr*p, namely llvm, which had no debug infos since I did a release build. llvm src was not updating because I used the old git repo location. Have the "fixed" c++ brainf*cked llvm now.
