Presumably coincidence. The apitrace crashes are segmentation faults, i.e. probably due to overrunning some buffer[0]. The Xorg crash is a bus error, which is probably fallout of the GPU hang. That said, we could probably confirm either way if we could look at a gdb backtrace of the Xorg crash. [0] FWIW, replaying the apitrace with valgrind on llvmpipe, I'm also seeing invalid memory access, so it might be a bug in apitrace or some shared Gallium / Mesa code rather than in the radeonsi driver.
