https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_12102/fi-pnv-d510/igt@i915_selftest@live@requests.html

gen3 hits it nearly 100% of the time in the live selftests.
IIRC it also looked like shard-snb has also hit it more
sporadically in some tests.

There's also at least one bug about it
https://gitlab.freedesktop.org/drm/intel/-/issues/4528
which I guess is why ci is able to ignore this, and that
then has enabled all the humans to ignore it as well.
