Looks like NOTOURBUG. But at the same time some memory management changes were made that might look like this. This needs confirmation as to whether it is still an issue on that machine with drm-tip.

Still failing on the same machine: $ : sudo -E ./gem_tiled_fence_blits --r normal IGT-Version: 1.20-g136100c (x86_64) (Linux: 4.14.0-rc4-drm-intel-qa-ww41-commit-36e0e80+ x86_64) Using 6145 1MiB buffers Received signal SIGSEGV.

With the same NOTOURBUG trace?
(In reply to Chris Wilson from comment #5) > With the same NOTOURBUG trace? Seems so, do you need further information (kern.log, dmesg, --debug in the test) or is definitely NOTOURBUG (Whose then, HW's?)? Thank you.
According to our results, this test haven't been failing since commit-6a58f7b+ and IGT-Version: 1.21-g94bd67c, so closing. Thanks.
