<pre>Setup:
* HW: SKL GT2 i5-6600K
* OS: Ubuntu 18.04
* SW: Git versions of drm-tip kernel, X server, SynMark2 v7.0
* Mesa: 68820007fddbb5b79f1b2b08e66ef14092053a95 (2019-09-18 15:16:36 radv: fix
loading 64-bit GS inputs)
Test-case:
* Run multiple times:
./synmark2 OglMultithread
Expected outcome:
* Works fine, as with i965 driver
Actual outcome:
* Half of the runs hit following assert:
src/gallium/auxiliary/util/u_inlines.h:87:pipe_reference_described: Assertion
`count != -1' failed.

title="NEW - (Only partly recoverable) GPU hangs in (multi-context) SynMark HDRBloom with Iris driver"
href="show_bug.cgi?id=111385">bug 111385</a>, I don't know when this issue started. That may also
have been affected by enabling VT-d (which allows kernel to enable GPU IOMMU).</pre>
