Description Eero Tamminen 2019-09-19 11:11:50 UTC
* 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)

* 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.

Because of bug 111385, 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).
