Add this patch into -queued commit cd9a8c405d532bb74c6e2431008161a05fd5cf84. The call trace goes away.

Can you retest without the patch and check how reliable you can hit this issue? Maybe you need the full testsuite run to provoke the exact timing that made things fail ... The WARN is expected as userspace is attempting to map a buffer that can only sometimes fit into the GTT (depending on GTT size and fragmentation due to pinned objects). So we should do: default: WARN(1, "unexpected error: %d\n", ret); case -ENOSPC: return SIGBUS; Fix merged to d-i-f: commit a7c2e1aad6c846f316641bbaa54cf999aeaa7ebc Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Oct 17 11:17:16 2012 +0200 drm/i915: shut up spurious WARN in the gtt fault handler Verified.
