*** Bug 99036 has been marked as a duplicate of this bug. *** Quite likely to be caused by: e9133dd90ec498cfb6a23fa22504e06488352c51 Author: Jordan Justen <jordan.l.justen@intel.com> CommitDate: Wed Dec 7 09:00:49 2016 -0800 i965: Increase max texture to 16k for gen7+ reducing the memory requirements allows the test to complete: https://lists.freedesktop.org/archives/piglit/2016-December/021581.html However, the lack of error recovery seems like a kernel bug. After this test is killed, subsequent GPU operations fail until reboot. Without reboot, the system will eventually hard-hang. Assigning to the kernel team, because it appears that OOM can kill a process while it holds a lock, generating an unrecoverable error. To reproduce: 1) use a device with 1GB RAM 2) use Mesa after e9133dd9, when texture sizes were increased 3) use piglit before 12b5938, when Ken reduced the memory footprint of fbo-maxsize You should see dmesg errors: "Unable to purge GPU memory due lock contention" Subsequently, other GPU workloads will fail intermittently.

That is not what that means at all. Updating title to reflect that this issue is not platform dependent. (In reply to Chris Wilson from comment #5) > That is not what that means at all.
