(In reply to lu hua from comment #0) [...] > Non-working platforms: i965 The attached dmesg indicates the machine has pciid=0x0412, which would be a HSW GT2 desktop. Is that the right dmesg?
The platform is irrelevant, the test exposes the pagefault-of-doom scenario in the current i915_gem_fault() implementation for all platforms.
Test on PNV, it also has this issue. It happens on all platforms.

Is that the right dmesg? i965 platforms include HSW.
